CLBO

CLBO


CLBO (Cesium Lithium Borate ) is a newly developed nonlinear optical crystal It is a scarce crystal which generate fourth harmonic and fifth harmonics of the Nd:YAG laser output. Due to high damage threshold it can be application in solid-state UV laser. Besides CLBO possesses small walk-off angle large acceptable angular spectral and temperature bandwidth
