Infrared nonlinear AGSe2 crystals, AgGaSe2(AgGa(1-x)InxSe2) Nonlinear Crystal has band edges at 0.73 and 18 µm. Its useful transmission range (0.9–16 µm) and wide phase matching capability provide excellent potential for OPO applications when pumped by a variety of different lasers. Tuning within 2.5–12 µm has been obtained when pumping by Ho:YLF laser at 2.05 µm; as well as non-critical phase matching (NCPM) operation within 1.9–5.5 µm when pumping at 1.4–1.55 µm. AgGaSe2 (AgGaSe) has been demonstrated to be an efficient frequency doubling NLO Crystals for infrared CO2 lasers radiation.

Applications of IR materials AgGaSe2:

• Generation second harmonics on CO and CO2 - lasers
• Optical parametric oscilator
• Different frequency generator to middle infrared regions up to 17 mkm.
• Frequency mixing in the middle IR region
