One of the first independent and privately owned companies in crystal growth industry in Russia. We are completely equipped with all necessary inventory, tools, machines and accessories for crystal growth and optical fabrication. Predictible, stable, efficient crystal growth in industrial manufacturing - this is the main result, and the main goal of our permanent research activity. Nowadays we are carrying out researches on finding new nonlinear crystals for laser frequency conversion from VIS into UV.

On-time delivery, use of the cutting-edge logistic technologies, participation in the World famous trade-shows and conferences - are the basic principles of our international activity. Long-term contract relations with the World leading laser manufacturing companies support our position of a relible vendor of nonlinear optics. Due to the fact of recognized superior quality of supplied LBO crystals, customers from different places of the World designate the desired material as "Russian LBO", and all other venodrs are compared with it.

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. More facts about LBO crystal applications .
