Bbo β Barium Metaborate Optical Crystal Mohs Hardness 4.5-5

BBO β Barium metaborate crystal

BBO (barium metaborate) crystal is a kind of crystal with obvious comprehensive advantages and good performance in nonlinear optical crystals. It has an extremely wide light transmission range, large phase matching supporting role angle, high light damage threshold, broadband temperature matching and excellent optical uniformity. Especially, it is widely used in frequency tripling of Nd: YAG lasers.

Main application:

(1) Used for second, third, fourth, and fifth harmonic generation of 1064nm Nd: YAG lasers.

(2) It is used for frequency doubling, frequency tripling, sum frequency and difference frequency of dye laser and Ti: sapphire laser.

(3) Used for optical parametric oscillation, amplifiers, etc.
