RTP EO cell
RTP is an ideal candidate for a wide variety of Electro-Optic applications as Pockels cells, shutters, Q-switch, phase modulators, attenuators, pulse pickers and more.
The outstanding electro-optical parameters allow extremely fast switching (rise/fall time under 1ns) and high repetition rates (over 1MHz) without ringing. RTP EO cells are assembled in a thermally compensated double-crystal configuration, in which two matched crystals are placed in line of the propagation axis (x or Y) with one rotated by 90 degrees. It performs well over a wide temperature range (from ‐50◦C to +70◦C). RTP is also non-hygroscopic which makes it robust in extreme conditions. The crystal is transparent at most common visible and near infrared laser wavelengths. RTP based EO devices are offered in matched pair configurations and in temperature compensating designs.Technical Data
