CLBO Crystal
The CLBO Crystal is transparent well into the DUV down to 180nm and allows type 1 SHG conversion up to 237nm and SFG below 190nm.
CLBO is optimal for DUV, combined with its low absorption, and high surface quality and LDT allows high-power DUV applications. CLBO has a relatively high nonlinear coefficient and low walk-off and is ideal for the 4th and 5th harmonic generation of ND: YAG and the 6th Harmonic of 1550nm. CLBO is an OXIDE productTechnical Data
CLBO (cesium lithium borate, CsLiB6O10) is a nonlinear optical crystal ideal for DUV light generation.
CLBO holds high transparency and low absorption in the DUV, High LIDT, relatively high coefficient, and low walk-off.
