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.

BBO Crystal (Beta-Barium Borate Crystal)
BBO crystal is an important nonlinear optical crystal with combination of unique optical properties. Broad transmission and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity provide attractive possibilities for various nonlinear optical applications.
UPT offers BBO specification:
LBO Crystal (Lithium Triborate Crystal)Note: OEM Dimension, different axis angle cutting and coating and damage threshold upon request others are available upon request.
LBO crystals is an excellent nonlinear crystal. For frequency doubling(SHG),tripling(THG) of Nd:YAG,Nd:YLF,Nd:YVO4 lasers, it is one of the most useful nonlinear optical materials in ultraviolet and visible laser applications.
Advantages:
broad transparency range from 160nm to 2600nm (see Figure 1);
high optical homogeneity (n10-6/cm) and being free of inclusion;
relatively large effective SHG coefficient (about three times that of KDP);
wide acceptance angle and small walk-off;
type I and type II non-critical phase matching (NCPM) in a wide wavelength range;
spectral NCPM near 1300nm.
high damage threshold(18.9 GW/cm 2 for a 1.3ns laser at 1053nm);
LBO has the highest damage threshold in all the commonly-used inorganic NLO crystals. Therefore, it is the best candidate for high average power SHG and other nonlinear optical processes.
