Lithium triborate (LiB3O5) LBO is an excellent non-linear optics crystal, which has a wide transparency range, high damage threshold, moderately high nonlinear coupling and desirable chemical and mechanical properties. LBO crystals have been widely used in second harmonic generation (SHG), for example of Nd:YAG lasers (1064 nm 532 nm). LBO can be both critically and non-critically phase-matched.
Thanks to its large spectral transmission range as well as noncritical phase matching (NCPM) in the near IR region, LBO crystals have been applied in non-linear optical applications like OPO, OPA, OPCPA and other. Since its broad gain bandwidth overlaps with Ti:Sapphire in 800 nm range, ultra-high power and high contrast laser systems have been built based on the mixed CPA/OPCPA plan.
