- efficient SHG of CO 2 laser (up to 9% conversion);
- for SHG of pulsed CO, CO2 and chemical DF-laser (l = 2.36 mkm) radiation;
- upconversion of CO and CO2 laser radiation into the visible range; infrared pulses generation via difference frequency mixing of Neodymium and infrared dye laser or (F-)-centre laser pulses;
- OPG light generation within 3.5 - 18 mkm.
Why GaSe geometry is special?
|Efficient generation of second harmonics of laser radiation 10,6 microns|
|Suitable for DFG from middle infrared regions up to 17 microns|
