LBO(Lithium Triborate, LiB3O5) is an excellent nonlinear optical crystal with combination of a number of unique features:
• Wide 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)
• High damage threshold(18.9 GW/cm² for a 1.3ns laser at 1.054μm)
• Wide acceptance angle and small walk-off
• Broad Type I and Type II non-critical phase-matching (NCPM) range
LBO crystal is perfectly suitable for various nonlinear optical applications:
• Frequency doubling (SHG) and tripling (THG) of Nd:YAG, Nd:YLF, Nd:YVO4, Nd:YAP lasers
• Frequency doubling (SHG) and tripling (THG) of Ti:Sapphire, Alexandrite and Cr:LiSAF lasers
• Optical parametric oscillators (OPO) of both Type I and Type II phase-matching
• Non-critical phase-matching for conversion of CW and quasi-CW radiation.

Notes:
• LBO has a very low susceptibility to the moisture. The dry conditions is required for both the use and preservation of LBO.
• LBO requires precautions to protect its polished surfaces.
• Bluebean Optical proviedes free holder for thin LBO crystal.
