CLBO


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.

Classification:


  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
