Silver Selenogallate (AgGaSe2) has band edges at 0.73 and 18 μm. Its useful transmission range lying within 0.916 μm and wide phase matching provide excellent potential for OPO applications when pumped by variety of currently available lasers. Tuning within 2.512 μm was obtained when pumped by Ho:YLF laser at 2.05 μm. It has also been shown as an excellent crystal for non-linear three-wave interactions.
|Large effective optical nonlinearity|
|Wide spectral and angular acceptances|
|Broad transparency range|
|High Figure of merit for non-linear interactions|
|Excellent crystal for three-wave interactions|
|Ultrashort pulse generation in mid IR range|
|Suitable for applications with CO2 laser|
