Today we found out about your Pismo Pulse Pickers, Electro-optical Ultrafast Shutters, products online.  We are putting in a proposal and need a quick, ball-park quotation for an ultrafast shutter to work with our Chameleon Ultra II Titanium:Sapphire laser.  The specifications we found online seem to be a very good match for what we are proposing to do. 

Del Mar Photonics comments:
You can see specifications and prices for several Pismo models in our online store.
The price mostly depends on the maximum pick up rate that you want to achieve.
For example here is a model for 10 KHz maximum pick up rate:

Pismo pulse picker
The Pismo pulse picker systems is as a pulse gating system that lets single pulses or group of subsequent pulses from a femtosecond or picosecond pulse train pass through the system, and stops other radiation. The system is perfectly suitable for most commercial femtosecond oscillators and amplifiers. The system can pick either single pulses, shoot bursts (patterns of single pulses) or pick group of subsequent pulses (wider square-shaped HV pulse modification). HV pulse duration (i.e. gate open time) is 10 ns in the default Pismo 8/1 model, but can be customized from 3 to 1250 ns upon request or made variable. The frequency of the picked pulses starts with single shot to 1 kHz for the basic model, and goes up to 100 kHz for the most advanced one.
The Pockels cell is supplied with a control unit that is capable of synching to the optical pulse train via a built-in photodetector unit, while electric trigger signal is also accepted. Two additional delay channels are available for synching of other equipment to the pulse picker operation. Moreover, USB connectivity and LabView-compatible drivers save a great deal of your time on storing and recalling presets, and setting up some automated experimental setups. One control unit is capable of driving of up to 3 Pockels cells, and this comes handy in complex setups or contrast-improving schemes. The system can also be modified to supply two HV pulses to one Pockels cell unit, making it a 2-channel pulse picker system. This may be essential for injection/ejection purposes when building a regenerative or multipass amplifier system.

I have received funding to buy a pulse picker. Our main application is selection of pulses from a ~ 100 MHz, 20 fs Ti:Sapphire laser (nJ/pulse energy levels), for which your Pismo 8/1 looks like the proper choice.
We might also wish to use the pulse picker on another application, which is to flip the polarization of a 1 kHz, 0.5 mJ amplified Ti:Sapphire laser (50 fs compressed pulse duration; it may be possible to operate on the uncompressed ~150 ps duration output as well). We would be flipping the polarization on alternating pulses (i.e. 500 Hz). I would like your comments on the technical feasibility of using the Pismo 8/1 for this application. If you feel that a larger aperture or other modifications are necessary, could you please also provide an estimate of cost on delivery on the modified item as well as on your standard product?
We look to issue a Purchase Order within the next few weeks.



Del Mar Photonics comments:
1) Full second-order dispersion of the pulse picker system (two Glan prisms (8x2=16 mm of calcite and electro-optical crystal, 16 mm of DKDP) is about 2100 fs^2. For example, the 100 fs (or 50 fs) input pulse (Gaussian pulse shape) at 800 nm will be chirped after the pulse picker system and will have duration about 115 fs (or 127 fs). Please see dispersion graph of dependence of input pulse duration and output pulse duration. Is it possible to introduce negative dispersion of this value in your setup before steering the pulses into the picker? We also have a pulse stretcher/compressor solution to do this if you are interested.
2) The second application can be fulfilled can be done with the same Pismo 8/1, however, you will need an external electrical TTL trigger signal. The external trigger signal must lead the optical pulse by 0.25-3 祍 and must be strictly locked to the optical train with jitter less than 200 ps. But if you have an amplifier, you can usually get such signal from its electronics.

AOTF Infrared Spectrometer
Del Mar Photonics offer a handheld infrared spectrometer based on the acousto-optic tunable filter (AOTF). This instrument is about the size and weight of a video camera, and can be battery operated. This unique, patented device is all solid-state with no moving parts. It has been sold for a wide variety of applications such as liquid fuel analysis, pharmaceutical analysis, gas monitoring and plastic analysis. Miniature AOTF infrared spectrometer uses a crystal of tellurium dioxide to scan the wavelength. Light from a light source enters the crystal, and is diffracted into specific wavelengths. These wavelengths are determined by the frequency of the electrical input to the crystal. Since there are no moving parts, the wavelength scanning can be extremely fast. In addition, specific wavelengths can be chosen by software according to the required algorithm, and therefore can be modified without changing the hardware. After the infrared radiation reflects off of the sample, it is converted into an electrical signal by the detector and analyzed by the computer. Del Mar Photonics is looking for international distributors for RAVEN - AOTF IR spectrometer for plastic identification and for variety of scientific and industrial collaborations to explore futher commercial potential of AOTF technology.

Femtosecond Transient Absorption Measurements system Hatteras Hatteras-D femtosecond  transient absorption data acquisition system
Future nanostructures and biological nanosystems will take advantage not only of the small dimensions of the objects but of the specific way of interaction between nano-objects. The interactions of building blocks within these nanosystems will be studied and optimized on the femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar Photonics, Inc. Thus we put a lot of our efforts and resources into the development of new Ultrafast Dynamics Tools such as our Femtosecond Transient Absorption Measurements system Hatteras. Whether you want to create a new photovoltaic system that will efficiently convert photon energy in charge separation, or build a molecular complex that will dump photon energy into local heat to kill cancer cells, or create a new fluorescent probe for FRET microscopy, understanding of internal dynamics on femtosecond time scale is utterly important and requires advanced measurement techniques.

Del Mar Photonics adaptive optics and wavefront sensors: ShaH-0620 wavefront sensor with telescope Wavefront Sensors: ShaH Family
A family of ShaH wavefront sensors represents recent progress of Del Mar Photonics in Shack-Hartmann-based technology. The performance of Shack-Hartmann sensors greatly depends on the quality of the lenslet arrays used. Del Mar Photonics. developed a proprietary process of lenslet manufacturing, ensuring excellent quality of refractive lenslet arrays. The arrays can be AR coated on both sides without interfering with the micro-lens surface accuracy. Another advantage of the ShaH wavefront sensors is a highly optimized processing code. This makes possible real-time processing of the sensor data at the rate exceeding 1000 frames per second with a common PC. Due to utilizing low-level programming of the video GPU, it is possible to output the wavefront data with a resolution up to 512x512 pixels at a 500+ Hz frame rate. This mode is favorable for controlling modern LCOS wavefront correctors.
The family of ShaH wavefront sensors includes several prototype models, starting from low-cost ShaH-0620 suitable for teaching laboratory to a high-end high-speed model, ShaH-03500. The latter utilizes a back-illuminated EM-gain CCD sensor with cooling down to -100癈. This makes it possible to apply such a wavefront sensor in astronomy, remote sensing, etc.

Frequency-stabilized CW single-frequency ring Dye laser DYE-SF-007 pumped by DPSS DMPLH laser installed in the brand new group of Dr. Dajun Wang at the The Chinese University of Hong Kong.
DYE-SF-077 features exceptionally narrow generation line width, which amounts to less than 100 kHz. DYE-SF-077 sets new standard for generation line width of commercial lasers. Prior to this model, the narrowest line-width of commercial dye lasers was as broad as 500 kHz - 1 MHz. It is necessary to note that the 100-kHz line-width is achieved in DYE-SF-077 without the use of an acousto-optical modulator, which, as a rule, complicates the design and introduces additional losses. A specially designed ultra-fast PZT is used for efficient suppression of radiation frequency fluctuations in a broad frequency range. DYE-SF-077 will be used in resaerch of Ultracold polar molecules, Bose-Einstein condensate and quantum degenerate Fermi gas and High resolution spectroscopy

Recogedores del pulso Definición: interruptores ópticos eléctricamente controlados usados para extraer solos pulsos de un tren de pulso Los pulsos ultracortos en la mayoría de los casos son generados por un laser modo-bloqueado bajo la forma de tren de pulso con un índice de repetición de pulso de la orden de 10 megaciclos - 10 gigahertz. Por varias razones (véase abajo), es a menudo necesario escoger ciertos pulsos de tal tren de pulso, es decir, para transmitir solamente ciertos pulsos y para bloquear todos los otros. Esto se puede hacer con un recogedor del pulso, que es esencialmente un interruptor óptico eléctricamente controlado. Tipos de recogedores del pulso Un recogedor del pulso es en la mayoría de los casos un modulador electróptico o un modulador acustóptico, combinado con un conductor electrónico conveniente. En el caso de un dispositivo electróptico, un recogedor del pulso consiste en una célula y una cierta óptica polarizante, e.g. un polarizador thin-film de Pockels; la célula de Pockels manipula el estado de polarización, y el polarizador después transmite o bloquea el pulso dependiendo de su polarización. El principio de un recogedor acustóptico del pulso es aplicar un pulso corto del RF al modulador acustóptico para desviar el pulso querido en una dirección levemente modificada. Los pulsos desviados pueden entonces pasar una abertura, mientras que se bloquean los otros. En todo caso, la velocidad requerida del modulador es determinada por la distancia temporal de pulsos en el tren de pulso (es decir por el índice de repetición de pulso de la fuente del pulso), algo que por la duración del pulso. El conductor electrónico de un recogedor del pulso puede satisfacer funciones adicionales. Por ejemplo, puede utilizar la señal de un fotodiodo rápido, detectando el tren de pulso original, para sincronizar la conmutación con los pulsos de entrada. Una señal del disparador puede entonces venir en cualquier momento, y la electrónica actuará en el interruptor en el momento apropriado para transmitir el pulso de entrada de llegada siguiente.

Usos de los recogedores del pulso Algunos usos típicos de un recogedor del pulso se describen en el siguiente: Para obtener altas energías de pulso en pulsos ultracortos, es con frecuencia necesario reducir la tarifa de repetición de pulso. Esto puede ser alcanzada colocando a un recogedor del pulso entre el laser de la semilla y el amplificador. El amplificador entonces actuará solamente en los pulsos queridos. Los pulsos bloqueados no constituyen necesariamente una pérdida de energía fuerte puesto que la energía media del laser de la semilla se puede pequeño comparar con el promedio de potencia de salida del amplificador, y la energía media restante puede ser suficiente para saturar el amplificador. En un laser cavidad-descargado, un recogedor del pulso (entonces a menudo llamado descargador de la cavidad) extrae el pulso de circulación de la cavidad en solamente cada Nth viaje de ida y vuelta. Durante el resto de viajes de ida y vuelta, el pulso experimenta pérdidas ópticas bajas y se puede amplificar a una alta energía. Un recogedor del pulso puede ser utilizado para la inyección y la extracción de pulsos en un amplificador regenerador. Características importantes de los recogedores del pulso Dependiendo del uso, diversas características de un recogedor del pulso pueden ser críticas: el tiempo de la conmutación (particularmente para las altas tarifas de repetición de pulso de entrada) la tarifa máxima de la repetición para la conmutación la pérdida de energía de pulsos transmitidos el grado de supresión de pulsos indeseados la anchura de banda óptica (particularmente para los pulsos de banda ancha) la dispersión cromática (particularmente para los pulsos de banda ancha, e.g. con duraciones bien debajo de 100 fs) la ausencia de linealidad óptica (particularmente para los pulsos con altas energías máximas) el tamaño de la abertura abierta las dimensiones externas la sensibilidad de la alineación (ángulo de aceptación) las capacidades del conductor electrónico correspondiente, e.g. referente a la sincronización Vea también: moduladores electrópticos, moduladores acustópticos, generación del pulso, tarifa de repetición de pulso, amplificadores regeneradores, pulsos ultracortos Categorías: dispositivos fotónicos, pulsos
