Examples of femtosecond lasers recently installed in various labs:
Trestles LH6-30 with multiharmonic generation unit
Trestles 100 femtosecond Ti: sapphire oscillator
Del Mar Photonics offers new Trestles fs/CW laser system which can be easily
switched from femtosecond mode to CW and back.
Having both modes of operation in one system dramatically increase a number of
applications that the laser can be used for, and makes it an ideal tool for
scientific lab involved in multiple research projects.

Schematic setup of Trestles LH10-fs/CW laser system with built-in pump laser
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 -

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.

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 lasers
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.
