RTP (Rubidium Titanyle Phosphate – RbTiOPO4) Crystals are an isomorph of KTP crystals and find great utility in nonlinear and electro-optical applications. It has the advantages of a higher damage threshold(about 1.8 times the magnitude of that of KTP), high resistivity, low absorption loss, non-hygroscopicity, and the absence of induced piezo-electric ringing with the frequencies of electrical input signals up to 60 kHz. Its transmission range is 350nm to 4500nm. The walk-off angle of the crystal, when generating yellow lasers, is miniature, in addition, the crystal is a highly efficient media for lasers of high repetition rates.
Hangzhou Shalom EO offers custom RTP crystals upon customers' request. AR coatings can be furnished. Besides, our RTP Q-Switches have been released for sale, click on the bold text to learn more.
