PT277 series laser systems integrate a picosecond optical parametric oscillator and DPSS pump laser into a single compact housing. Mounting the components into one frame provides a cost-effective and robust solution with improved long-term stability and reduced maintenance costs.
The tuning range is for the model PT277 1400 – 2050 and 2200 to 4450 nm with nearly Fourier transform limited linewidth.
The microprocessor-controlled wavelength tuning is fully automatic. The wavelength controlling elements are mounted on precise micro‑stepping motors. The temperature of the non‑linear crystal is controlled by a precise thermocontroller with a bidirectional Peltier element, resulting in the fast tuning of crystal temperature. For customer convenience the system can be controlled through its USB type PC interface (RS232 is optional) with LabView™ drivers or a user-friendly remote control pad. Both options allow easy control of system settings.

Note: Laser must be connected to the mains electricity all the time. If there will be no mains electricity for longer that 1 hour then laser (system) needs warm up for a few hours before switching on.
