Del Mar Photonics supply Trestles lasers as stand alone system, or as a one-box system with built-in DPSS pump laser.
The price of the system with DPSS pump depends on required output power.

The standard tuning elements indicated below are used in CW Ti:Sapphire lasers such as Trestles CW or Trestles fs/CW.

Those elements are also sold separately as standrad items or as a custom made components.

1) Thick etalon - request a quote
Thickness - 3 mm, diameter - 20 mm. Surface quality: Ð=1-2, N<1, ΔN<0.1,
λ/10, plane parallelism better than 10''. Thickness accuracy 5 um.

2) Thin etalon - request a quote
Thickness - 200 um, diameter - 15 mm. Surface quality: Ð=1-2, N<1, ΔN<0.1,
λ/10, plane parallelism better than 10''. Thickness accuracy 5 um.

3) Birefringent filter BRF - request a quote

We use a 3-plate assembled BRF (Lyot filter) with adjustable motorized mount (see attached drawing).

Total losses introduced into the cavity by the filter are 5% of the laser抯 output power. The FSR is defined by the thinnest plate and equals to around - 1.3*1014 Hz, while the maximum width is controlled by the thickest plate and equals to approx. 3.1*1012 Hz.

Dimensions of plate assembly ('filter' in the picture): dia 44.5 mm, t=13.5 mm. It should be properly aligned (Brewster to the beam) and rotated by some rotating mount around its axis to provide wavelength tuning.

Third and Forth Harmonic Generator for Ti:Sapphire lasers: Three Case studies

Customer inquiry:

We have about 1 W across the range 780nm to 920 nm. We are interested mostly in tunability in the range 240-300nm. Pulse width is not very > important. If a (third + fourth) HG exists in one model, that would be great. Also it would be good for us to have several wavelength available at the same time, i.e. fundamental and harmonics.
I want to use this system for a photoemission microscope, and my first interest is in the tuning capability. The second interest is in building up a pump-and-probe system using the fundamental or 2nd harmonic as a pump beam and the third harmonic as probe. Do you have suggestions for the delay-line?

Answer:
We can offer our multiharmonic (SH, TH) generator unit. The simultaneous output will have around 10% (100 mW) of your input power in fundamental and each of harmonics (10% fundamental, 10% second and 10% third). Each harmonic has its own output (see attachment). The tuning range will be 260-300 nm for TH with your input tuning range.
The FH system will produce 205-230 nm radiation out of your laser (780-920)

Customer inquiry:
I'm interested in the 3^rd harmonic generator for an amplified Ti:sapphire laser. What is the maximum pulse energy? The system is a Coherent regenerative amplifier (RegA 9000) that produces 750 mW at a repetition rate of 100 kHz, which is a pulse energy of 7.5 microjoules in 50 femtoseconds. The beam diameter is 2.7 mm.

We have tried to use a Coherent 9300 harmonic system, but it is designed for oscillator energies of nanojoules, so it is too tightly focused on the crystal and generates white light.


Answer:

Please find enclosed the quotation for the TH generator along with the drawing. Please note that since the unit is non-standard the dimensions may be extended by +100 mm in length and +50 mm in width.

Third harmonic generator (THG) is developed for frequency doubling and tripling of Ti-Sa amplifier radiation (λ=780-820 nm). Device is based on second harmonic generation (SHG) and sum-frequency generation (SFG) techniques and provides stable radiation in fs scale. TH generator is developed for high conversion efficiency.
