Beta Barium Borate (BBO) crystal is a Nonlinear Optical Crystal with a combination of unique features: wide transparency region, broad phase-matching range, large nonlinear coefficient, high damage threshold, wide thermal acceptance bandwidth and high optical homogeneity. High power BBO Pockels Cells from Crystro is usually used in the area of high power q switched Pulsed Laser.
E-O Q Switch of EOQ series are transverse field devices. Low electro-optical coefficient of BBO results in high operating voltages. The quarter-wave voltage is proportional to the ratio of electrode spacing and crystal length. As a result, a smaller aperture device has lower quarter-wave voltage. However, even for 3mm aperture devices quarter-wave voltage is as high as 3.4KV@1064nm. Double crystal design is employed in order to reduce required voltages and allowing operation in half-wave mode with fast switching times.
