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 opeartion 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.

Typical specifications are:

Trestles fs/CW laser system
Ti:Sapphire femtosecond oscillator with CW operation option
Spatial mode: TEMoo;
Polarization: linear horizontal;
fs mode:
Tuning range (@10W pump): 750-850 nm;
Output power (@10W pump, 800 nm): >1500 mW;
Repetition rate: 80 MHz;
Pulse duration: <100 fs;
CW mode:
Tuning range (@10W pump): 750-850 nm;
Output power (@10W pump, 800 nm): >2000 mW in CW;
Linewidth (with two etalons): <2 GHz
Also included:
Thermostabilized breadboard;
Electronic starter with TTL output for mode-locked mode observation;
USB-controlled tuning slit for wavelength tuning in fs mode;
3-plate USB-controlled birefringent Lyot filter;
Two motorized USB-controlled etalons for linewidth control

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.
