Our RTP (Rubidium Titanyl Phosphate) electro‐optic crystals can be used for a wide variety of applications in industrial, medical, and range-finding. The crystals are transparent from the visible to near infrared laser wavelengths. They can be used under low half-wave voltage for electro-optic cells, and can sustain large laser induced damage and low absorption losses. The performance is guaranteed and consistent over a wide temperature range (from ‐50ºC to +70ºC) and high repetition rates.


  • Low half-wave voltage

  • Short rise time, fall time and pulse width

  • High laser induced damage threshold

  • Non-hygroscopic, easy handling, no cover needed.

  • Low absorption losses at 1064nm

  • High homogeneity
