RTPEO Cells

Used for electro-optics applications, RTP crystals offer superior properties for users in the
aerospace, defense, medical, industrial, civil and scientific applications.
RTP EO Cells are assembled in a thermally compensated double-crystal configuration, in which
two matched crystals are placed in line of the propagation axis (X or Y) with one
rotated by 90 degrees (general drawing below).
Advantages
- Low half-wave voltage for EO Cells to enable a compact design
- Rise time, fall time, and pulse width of 1 ns to enable fast operation
- Designed to operate over wide temperature range (-50°C to 70°C)
- High laser-induced damage threshold (up to1000 MW/cm2, at 1064 nm, 10 ns pulse)
- Minimal ringing, compatible for 1 MHz repetition rate
- The best material in the spectral range of 500-3000 nm for electro-optics applications
- Very low absorption losses at 1064 nm wavelength
- Extremely high homogeneity: up to 15*15 mm EO cells as a standard size
