Product description
RTP (Rubidium Titanyle Phosphate – RbTiOPO4) is an isomorph of KTP crystal which is used in nonlinear and Electro Optical applications. It has advantages of higher damage threshold(about 1.8 times of KTP), high resistivity, high repetition rate, no hygroscopic and no piezo-electric effect. Its high electrical resistivity is important for many electro-optical applications. Its transmission range is 350nm to 4500nm.
Through years of research and development, CRYSTECH has achieved great advances in growing techniques of RTP crystals.  We are able to provide excellent RTP crystals both in matched pairs or single crystals.
