Detailed introduction

　　CLBO(Cesium Lithium Borate,CsLiB₆O₁₀) is a newly developed crystal with excellent UV nonlinear feature. Compared to BBO, it has larger spectral and temperature acceptance, larger angle tolerance and smaller walk-off angle.

　　PRODUCT FEATURE

　　● 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

APPLICATIONS

　　● PCB drilling

　　● Semiconductor lithography

　　● Optical parametric oscillator

　　● All solid-state UV laser
