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.

Autocorrelator Reef RT, Del Mar Photonics, San Diego, CA
Reef femtosecond autocorrelators
The autocorrelation technique is the most common method used to determine laser pulse width characteristics on a femtosecond time scale.
The basic optical configuration of the autocorrelator is similar to that of an interferometer (Figure.1). An incoming pulse train is split into two beams of equal intensity. An adjustable optical delay is inserted into one of the arms. The two beams are then recombined within a nonlinear material (semiconductor) for two photon absorption (TPA). The incident pulses directly generate a nonlinear TPA photocurrent in the semiconductor, and the detection of this photocurrent as a function of interferometer optical delay between the interacting pulses yields the pulse autocorrelation function. The TPA process is polarization-independent and non-phasematched, simplifying alignment.

Reef-RT autocorrelator measures laser pulse durations ranging from 20 femtoseconds to picosecond regime. It measures pulse widths from both low energy, high repetition rate oscillators and high energy, low repetition rate amplifiers. Compact control unit operates autocorrelator head and optional spectrometer through on-screen menus. Autocorrelation trace and spectrum can be displayed and analyzed on screen or downloaded to remote computer.

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.
