Trestles Opus femtosecond Ti:Sapphire laser with built in 3 Watt DPSS laser

Trestles Opus is a Ti:sapphire oscillator that produces laser pulses with a duration from 50 to 100 femtoseconds at an average power up to 400 mW at 800nm. Spectrally limited (also called transform-limited) 100 fs pulses have minimal broadening in multiphoton microscope systems and doesn't require any additional dispersion management pulse chirping apparatus. It is tunable in the range and also available with any fixed center wavelengths of 750, 770, 790, 810, 830, 850, or 870 nm and any other wavelengths in between.
The Trestles Opus comes with 2 years warranty. New femtosecond source is priced under 50 thousand dollars. (request a quote)

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 - 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’s 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.
