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.


  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
