United Photonics Technology
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.
Advantages:
Broad transparency range from 160nm to 2600nm (see Figure 1);
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.
