Efficient generation of second harmonics of laser radiation 10,6 microns
Suitable for DFG from middle infrared regions up to 17 microns
Description
Wide transmission region from 650 nm to 18000 nm
GaSe has been successfully used for 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. It is impossibile to cut crystals for certain phase matching angles because of material structure (cleave along (001) plane) limiting areas of applications.
