Introduction

Cesium Lithium Borate (CsLiB₆O₁₀ or CLBO) is a newly developed crystal with excellent UV nonlinear feature, and widely used for semiconductor inspection, micro processing, bio-medical, UV-LiDAR, etc. Compared to BBO, it has larger spectral and temperature acceptance, larger angle tolerance and smaller walk-off angle (see Table 1). These advantages make CLBO obtain larger SHG conversion efficiency than BBO. Moreover, it is suitable for FOHG and FIHG of high-power Nd:YAG laser.

CASTECH'S CLBO is featured by

• ??Cut-off wavelength up to 180 nm;
• ??Maximum FOHG and FIHG conversion efficiencies of Nd doped laser;
• ??Relatively large effective NLO coefficient (about two times that of KDP);
• ??Wide acceptance angle and small walk-off angle;
• ??The VUV output at 193 nm is available by phase matching;
• ??No saturation for high-power generation;
• ??Short grow cycle and large size.
