Over the last few years LBO crystal has become the material of choice for high power laser applications from the UV to NIR.
LBO (Lithium Triborate – LiB3O5) is now the most popularly used material for Second Harmonic Generation (SHG) of 1064nm high power lasers (as a substitute to KTP) and Sum Frequency Generation (SFG) of 1064nm laser source to achieve UV light at 355nm.
LBO crystal also has the advantage to be used in Non Critical Phase-Matching configuration (no walk-off) at certain temperatures (around 150°C for SHG of 1064nm). Recent development of our crystal growing technique now allows us to process crystals with apertures of several cm².
It has a wide transparency range, moderately high nonlinear coupling, high damage threshold and desirable chemical and mechanical properties.
