GaSe Crystals

Manufacturer's part number :


Manufacturer Altechna


Description :

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.
