BBO Electro-optic Q-Switch

For high-average power and high repetition rate applications, BBO electro-optic Q-Switch from Coupletech are the preferred alternative to KD*P pockels cells. BBO based pockels cells operate from approximately 0.2 - 2.1 µm and are not subject to tracking degradation. BBO,which has low piezoelectric response, good thermal stability, and low absorption. Due to the low piezoelectric coupling coefficients of BBO cells function at repetition rates of hundreds of kilohertz. These Pockels cells work in regenerative amplifiers, high pulse repetition rate micro-machining lasers and high-average power lasers for material processing and metal annealing.   BBO CPLBQS-03025 is single crystal cells which has 3 x 3 x 25 mm, the aperture is 2.6mm, quarter-wave voltage is about 3000V, without protecting windows. Repetition rate is 1 ~  1MHz.
