Lithium triborate (LiB₃O₅ or LBO) 

 Lithium triborate (LiB₃O₅ or LBO) is an excellent nonlinear optical crystal for many applications.
It is grown by an improved flux method.

                                                      

AOTK's LBO Advanced Properties
● High damage threshold (18.9 GW/cm², 1.3ns pulse-width at 1053nm)
● Very small walk-off angle
● Wide acceptance angle
● Broad transparency range from 160nm to 2600nm (SHG range from 550nm to 2600nm)
● High optical homogeneity (Dn » 10^-6/cm) and free of inclusion
● Relatively large effective SHG coefficient (over 3 times than that of KDP)
● Both type I and type II non-critical phase-matching (NCPM) in a wide wavelength range

Typical Applications of LBO
 ● SHG of high power Nd:YAG and Nd:YLF lasers for R&D and military
 ● SHG of diode laser pumped Nd:YVO₄, Nd:GdVO₄, Nd:YAG and Nd:YLF lasers
 ● SHG of Ti:Sapphire, Alexandrite and Cr:LiSAF lasers
 ● SHG of medical and industrial Nd:YAG lasers
 ● Frequency-tripling (THG) of Nd:YAG and Nd:YLF lasers
 ● Frequency-doubling (SHG) and -tripling (THG) of high power Nd:YAP laser at 1340 nm
 ● Optical parametric amplifiers (OPA) and optical parametric oscillators (OPO) by
   harmonics of Nd:YAG lasers and Excimer lasers
