LBO
LBO crystals is an excellent nonlinear crystal.For frequency doubling(SHG),tripling(THG) of Nd:YAG,Nd:YLF,Nd


Lithium Triborate (LBO) crystals is an excellent nonlinear crystal. For frequency doubling(SHG), tripling(THG) of Nd:YAG,Nd:YLF,Nd:YVO4 lasers, it is one of the most useful nonlinear optical materials in ultraviolet and visible laser applications.


Advantage:


• broad transparency range from 160nm to 2600nm;

• high optical homogeneity (δn≈10-6/cm) and being free of inclusion;

• relatively large effective SHG coefficient (about three times that of KDP);

• wide acceptance angle and small walk-off;

• type I and type II non-critical phase matching (NCPM) in a wide wavelength range;

• spectral NCPM near 1300nm.

• high damage threshold(18.9 GW/cm 2 for a 1.3ns laser at 1053nm);    

LBO has the highest damage threshold in all the commonly-used inorganic NLO crystals. Therefore, it is the best candidate for high average power SHG and other nonlinear optical processes.
