CRYSTECH RTP Q-switch
RTP (Rubidium Titanyl Phosphate - RbTiOPO4) is a very desirable crystal material for electrooptic modulators and Q-switches. Due to its natural birefringence, It always works in pairs which are carefully matched to compensate the birefringence. The laser light propagates either in X-axis or Y-axis, and is polarized along the diagonal of the input face, and is rotated by 90° in the second crystal. The "slow" ray in the first crystal then becomes the "fast" ray in the second and the total static birefringence is thus in theory cancelled in the crystal pair. RTP is most suited to moderate average power laser sources where high repetition rates and short Q-switched pulse lengths are more important than high average powers.
