CLBO Crystal Basic characteristics
CLBO, or cesium lithium borate crystal (CsLiB₆O₁₀), is a high-performance new nonlinear optical crystal. Its broad transmission range, high nonlinear coefficient, wide spectral and temperature acceptance bandwidths, and absence of second-harmonic absorption make it outstanding for high-power laser frequency conversion and deep-ultraviolet generation.

Atomic Density [Nd1.0%]: 1.26x1020 atoms/cm3 (Nd1.0%) Crystal Structure: Zircon Tetragonal, space group D4h-I4/amd a=b=7.1193A,c=6.2892A Density: 4.22g/cm3
Nd:YVO4 is one of the most promising commercially available diode pumped solid state laser materials. It has high laser induced damage threshold and good mechanical in addition to optical properties. Its large stimulated emission cross-section and high absorption of pump laser make it a right crystal for pocket laser. Nd: YVO4 can produce IR green and blue laser by using minor different set-up. A broad absorption band centered at 808nm and favorable mechanical properties make Nd:YVO4 well suited for compact, efficient, high power diode-pumped lasers. Natural birefringence gives rise to a highly polarized output at 1064.3 and 1342nm.
