Particularly compact, all-in-one and air-cooled nanosecond OPO-laser system pumped by an M-NANO-GREEN as the front end.  This product was developed in close collaboration with GWU-Lasertechnik in Germany.


The OPO (optical parametric oscillator) is manufactured by GWU-Lasertechnik in Germany, a renowned maker of OPO systems with many years of profound experience in this technology.


This OPO laser includes all electronics/drivers and cooling (air-cooling) and is ready-to-operate without any further driver or coolers, just provide the 24 VDC and perhaps some commands and the pulses come out!


The >20-mJ-level output (@ 690 nm) is available at the fiber bundle port (fiber-bundle is customer specific) or (optional) free-space output port #1, the residual 1064 nm with up to >100 mJ from the pump laser is available at the other port #2.


Fast wavelength switching is available: this OPO laser can switch the wavelength between two or more wavelengths on a shot-to-shot basis.


This particularly small and all-in-one OPO laser unit is suited for space-constrained and mobile applications (total weight ca. 16 kg), its size allows integration into a 19" rack housing.


A trigger output is provided which has a low delay and low jitter (<~1 ns) with respect to the actual laser pulse emitted.


The digital interfacing to this OPO laser unit is possible via RS232 commands or by USB. A software GUI is included as well as a 24VDC power supply for easy setup and control from a Windows PC (Win 10 upwards requirement, PC not included).


Benefits: Size and weight are exceptionally small for the laser output parameters reached and allows integration into compact and mobile setups or instruments.


Applications: Photo-acoustic imaging; Fluorescence; LIDAR; Illumination; Research and Others.
