Due to the very high nonlinear optical properties, the LBO crystal is very suitable for harmonic generation of high-intencity laser radiation in vacuum ultraviolet and visible spectrum. LBO allows to achieve the highly efficient SHG of nanosecond, picosecond, cw and diode laser pumped Nd:YAG and Nd:YLF lasers for R&D, medical, industrial and military applications. The superiority of LBO is proved for the SHG of Ti:Sapphire, Alexandrite and Cr:LiSAF laser radiation as well as for optical parametric amplifiers and oscillators pumped by Excimer lasers and harmonics of Nd:YAG lasers. To have a good transmission in the UV allows to obtain tunable UV and VUV radiation by SFG in LBO.
