LBO crystal is an excellent nonlinear optical crystal for frequency doubling (SHG) tripling (THG) of Nd:YAG, Nd:YLF and Nd:YVO4 lasers, its transmission range is from 0.21 um to 2.3 um. It is one of the most useful nonlinear optical materials inultraviolet and visible laser applications, it allows temperature-controllable non-critical phase matching for 1.0-1.3 um, Type I SHG, and also provides room temperature NCPM for Type II SHG at 0.8-1.1um.
Advantages:
Broad transparency range from 160nm to 2.6um
High optical homogeneity (dn»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 in a wide wavelength range
Spectral NCPM near 1300nm
High damage threshold
Applications:
Medical and industrial filed of Nd:YAG lasers,Ti:Sappire and Cr:LiSAF lasers
Scientific research and military filed of high power Nd:YAG, Nd:YLF lasers
OPO and OPA, SHG, THG for high power 1340nm Nd:YAP lasers
