OEM Manufacturer Large Nonlinear Coefficients Zgp Crystal - AgGaSe2 Crystals – Dien
OEM Manufacturer Large Nonlinear Coefficients Zgp Crystal - AgGaSe2 Crystals – Dien Detail:
AgGaSe2 crystals have 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 (AgGaSe2) has been demonstrated to be an efficient frequency doubling crystal for infrared CO2 lasers radiation.
• Generation second harmonics on CO and CO2 - lasers
• Optical parametric oscillator
• Different frequency generator to middle infrared regions up to 18 um.
• Frequency mixing in the middle IR region
Standard cross sections are 8x 8mm, 5 x 5mm, Crystal length range from 1 to 30 mm. Custom sizes are also available on request.
