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 induce piezo-electric effect with electrical signals up to 60 kHz. Its transmission range is 350nm to 4500nm. Hangzhou Shalom EO offers the custom RTP crystals upon customer's request.
Reliable homogeneity and high laser damage threshold
Non-hygroscopic and low absorption losses
No acoustic ringing and stability over a wide temperature range(-60℃-+80℃)
