Lithium triborate (LiB3O5, LBO) crystal

non-linear opticallaser

Our LBO has extremely low absorption at the wavelengths of interest, 1064 and 532 nm. We can provide material with absolute absorption of ~ 1 ppm/cm at both wavelengths. Laser damage threshold of our LBO crystals is record high, e.g. Its bulk LIDT at 532 nm, 15 ns is >50 GW/cm2. We have developed exceptional polishing procedures, which guarantee very low subsurface damage and super-polish finish of a crystal surface. We can readily achieve RMS surface roughness of 2 Angstroms. Our coating capabilities encompass IBS, e-beam and magnetron anti-reflective techniques. The processes are perfected to yield coatings with ultra-low reflectivity and absorption. We engineered coatings with absorption as low as 2 ppm and reflectivity less than 100 ppm (0.01%) at 1064 nm. Finally, we offer LBO optical crystals with superior bulk quality and the best surface quality available today in the marketplace.
