LBO (Lithium triborate or LiB3O5) is a very useful nonlinear optical crystal material, especially for SHG THG of high-intensity laser radiation, intracavity SHG THG, deep-UV SFG and OPO applications.

Item: Nonlinear Optical Crystal LBO

Advantages of LBO

• Wide transparency,. High nonlinear coupling, good chemical and mechanical properties
• Type I and type II non-critical phase-matching (NCPM) over a wide wavelength range.
• High damage threshold(18.9 GW/cm² for a 1.3ns laser at 1054nm)
• Wide acceptance angle and small walk-off angle
• High optical quality (homogeneity≈10^-6/cm)

Applications of LBO

• High power Nd:YAG and Nd:YLF lasers for R&D and military applications
• Ti:Sapphire, Alexandrite and Cr:LiSAF lasers
• Medical and industrial Nd:YAG lasers
• Frequency-tripling (THG) of Nd:YAG and Nd:YLF lasers
• OPA and OPO pumped by Eximer lasers and harmonics of Nd:YAG lasers
• Frequency doubling (SHG) and tripling (THG) of high power Nd:YAP laser at 1.34μm.
