BIBO Laser Crystals

BIBO( BiB3O6) Crystal is a newly developed Nonlinear Optical Crystal. It
features a large effective nonlinear coefficient, a high damage threshold, and
inertness to moisture. Its nonlinear coefficient is 3.5-4 times higher than
that of LBO, and 1.5-2 times higher than that of BBO. It is a promising SHG
crystal to generate blue laser output.

Applications of BIBO Laser Crystals

SHG and THG for medium and high power Nd: lasers at 1064nm

SHG and THG of high power Nd: lasers at 1342nm & 1319nm

SHG for the Nd: Lasers at 914nm & 946nm

Optical Parametric Amplifiers (OPA) and Oscillators (OPO) application
