Lithium triborate (lbo) crystal, due to its high damage threshold, wide angular acceptance, relatively small walk-off and non-critical phasematching capability to generate second harmonic with no walk-off, has become a material of choice for generating harmonics in solid state lasers. Core optronics offers shg and thg, ar coated lbo crystals with high damage threshold and longterm stability. Attractive prices directly from factory. Our capabilities include: Growth of pure, ultra low absorption lbo crystals Precision crystal surface cutting Perfect surface grinding and polishing We use ion beam sputtering for deposition of dielectric antireflection (ar) coatings. Years of experience in thin film r&d and over 7 years of innovation in crystal growth and optical fabrication These combined capabilities result in superior performance of our lbo products, developed for high power dpss and lamp pumped lasers. Our lbo specifications: Material: lbo, other on request Coating technology: ibs with in-situ ion beam sputter cleaning Coating spectral range: 200 to 2000nm Damage threshold: >1gw/cm2 @ 10ns, 10hz, 1064nm, >400mw/cm2 @ 10ns, 10hz, 308 nm Reflectivity: Vvv coating:
