RTP (Rubidium Titanyl Phosphate - RbTiOPO4) is a very desirable crystal material for E-O modulators and Q-switches. It has advantages of higher damage threshold (about 1.8 times that of KTP), high resistivity, high repetition rate, no hygroscopic or piezoelectric effect. As biaxial crystals, RTP’s natural birefringence needs to be compensated by use of two crystal rods specially oriented so that beam passes along the X-direction or Y-direction. Matched pairs (equal lengths polished together) are required for effective compensation.
RTP Pockels cells are widely used in laser ranging, laser lidar, medical lasers and industrial lasers, etc.
WISOPTIC provides technical consultation, optimized design, customized test sample, and fast-delivery standard products of RTP Pockels cells.
