BBO Crystal

BBO crystal is a kind of crystal with good comprehensive advantages and good performance in nonlinear optical crystals. It has a wide range of light transmission, large matching angle, high resistance to light damage threshold, wide temperature matching and Excellent optical uniformity, especially for the triple frequency of Nd:YAG lasers, has a wide range of applications.

Second, third, fourth and fifth harmonic generation.
Frequency double, tripling and mixing of Dye and Ti:Sapphire lasers.
Optical parametric amplifiers (OPA) and optical parametric oscillators (OPO).
◇Broad phase-matching wavelength range from 409.6nm to 3500nm.
◇Wide transmission region from 190 nm to 3500nm.
◇Large effective SHG coefficient about 6 times greater than that of KDP crystal.
◇High damage threshold of 10 GW/cm2 for 100 ps pulse-width at 1064nm.
◇High optical homogeneity with ∆n ~ 10-6/cm.
◇Wide temperature-bandwidth of about 55°C.(For type I SHG 1064nm).
◇Good Mechanical and physical properties.
