CLBO: CsLiB6O10
Composition：CLBO(CsLiB6O10）Crystals (Caesium lithium borate)
Advantages
- Short cut off Wavelength (180nm)
- Large Angle Tolerance
- Small Walk-off Angle
- No Saturation for High-Power Generation
- Superior harmonic generator in UV region (4HG & 5HG of Nd:YAG, Shortest Type I SHG:237nm)
- High bulk laser damage threshold (>1.7 times higher than fused quartz @266nm)
- Large d coefficient:d36(532nm)=0.92pm/V ⇒Good for high-power UV applications
Advantages compared to BBO
- High conversion efficiency due to small walk-off
- Wider transparent range: 180～2750nm ⇒Particularly suited to DUV generation
