Optoelectronics & Engineering Services BBO Pockels Cell HIGHLIGHTS • High Repetition Rate • High repetition rate DPSS Q-Switch • High peak power damage resistance • High repetition rate Regenerative Amplifier control • Cavity Dumping • Beam Chopper The EOQ-BBO series Pockels cells are transverse field devices. The low electrooptical 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. A double crystal design is available in order to reduce required voltages and allowing operation in half-wave mode with fast switching times. BBO is one of the electro-optic material choices for high average power pockels cell applications. BBO has significant advantages over other materials in terms of laser power handling abilities, temperature stability, and substantial freedom from piezoelectric ringing. Because it relies on the electro optic effect, switching time - aided by the low capacitance of the Pockels cell is very fast. The wide transparency range of BBO allows it to be used in diverse applications. Artifex Engineering Dortmunderstr. 16-18 26723 Emden, Germany mail: info@afx-eng.com http://www.afx-eng.com
