LBO crystal by Cristal Laser manufacturer


LBO crystal
(Lithium Triborate – LiB3O5) has become the material of choice for high power laser applications from the UV to NIR.

Nonlinear LBO crystals, LBO crystal have wide transparency region, Broad type 1 and type 2 NCPM, small walk-off angle and high damage threshold.

Lithium Tri-borate Crystal

It is unique in many aspects, especially its wide transparency range, moderately high non-linear coupling, high damage threshold and good chemical and mechanical properties. Its transmission range is from 0.16m to 2.6m.
LBO crystals allows temperature-controllable non-critical phase-matching (NCPM) for 1.0-1.3 m, Type I SHG, and also provides room temperature NCPM for Type II SHG at 0.8-1.1 m. It possesses a relatively large angular acceptance bandwidth, reducing the beam quality requirements for source lasers.
