BBO Crystal

As a superior electro-optical material, BBO crystal is often used in high-power laser systems with wavelengths from 200nm to 12500nm. Z-cut BBO crystals, after being coated with anti-reflection coating and electrodes with gold plating, can be used as Q-switched devices for continuous-wave diode pumped Nd:YAG lasers to produce high-power energy output. Our company can provide BBO sheets with a thickness of 0.05 mm.
