Cesium Lithium Borate (CsLiB6O10£¬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 efficiencies than BBO. Moreover£¬it is suitable for FOHG and FHG of high-power Nd:YAG laser.
CLBO is featured by£º
? Cut-off wavelength up to 180nm£»
? Maximum FOHG and FHG conversion efficiencies of Nd:YAG laser£»
? Relatively large effective NLO coefficient (about two times that of KDP)£»
? Wide acceptance angle and small walk-off angle£»
? The VUV output at 193nm is available by phase matching£»
? No saturation for high-power generation£»
? Short grow cycle and large size.??
? Strict quality control;
? Cut angle and dimensions upon request;
? AR-coating£¬sealed-housing and repolishing services;
? Fast delivery (10 working days for polished only£¬15 working days for AR-coated).
