CLBO (Cesium Lithium Borate CsLiB6O10) – Laser Crystal – Nonlinear Crystal – Customized Products

CLBO (Cesium Lithium Borate, CsLiB6O10) is a new type of nonlinear crystal. It has a wide transparent spectral range (175~2800 nm), a high nonlinear coefficient, 2.2 times that of KDP, and a small dispersion angle.

The laser damage threshold is high, up to 26GW/cm2, and the multiplicative conversion efficiency is 60% (SHG). It can work at room temperature and is well suited for Nd: YAG lasers to produce 4w (266 nm) and 5w (213 nm) octave light output. It can be used for UV parametric oscillation (OPG) and parametric amplification (OPA).
