AGSe (AgGaSe2) Nonlinear Crystal
AGSe (AgGaSe2) Nonlinear Crystal
AgGaSe2 silver selenide crystal, referred to as AGSe crystal for short, is one of the most effective crystal materials for frequency doubling of mid-infrared laser, and it also has excellent performance of three-wave nonlinear interaction (OPO). The useful light transmission range of AGSe crystal is 0.9-16μm, and it has wide phase matching ability. With the mature laser pumping, the OPO of AGSe crystal shows wide infrared tunable performance. Pumping AgGaSe2 crystal with Ho:YLF 2.05μm to obtain 2.5-12μm OPO tuned light source; Non-critical phase matching OPO pumped by 1.4-1.55 μm tuning light source outputs 1.9-5.5 μm tuning light source; Frequency doubling of pulsed CO2 laser.
Key Features and Applications
- AgGaSe2 crystal has high frequency doubling efficiency for mid-infrared lasers
- AGSe crystals can be used for optical parametric amplification, optical parametric oscillation, and difference frequency generation, with application wavelengths up to 16μm in the mid-infrared.
- Basic characteristics of optical narrowband filtering of silver gallium selenide crystals near the isotropic point
