Product Details

LiNbO₃ crystal is a low cost photoelectric material with good mechanical and physical properties as well as high optical homogeneity. It has been widely used as frequency doublers for wavelength > 1mm and optical parametric oscillators (OPOs) pumped at 1064nm as well as quasi-phase-matched (QPM) devices. With preferable E-O coefficients, LiNbO₃ crystal has become the most commonly used material for Q-switches and phase modulators, waveguide substrate, and surface acoustic wave (SAW) wafers, etc. Compared with LiNbO₃, MgO:LiNbO₃ crystal exhibits higher damage threshold.

LiNBO₃ Pockels cells address wavelengths from 1.064 μm through infrared as long as 4.0 μm. They operate at lower voltages than comparable KD*P cells, though the voltages increase at the longer wavelengths. Piezoelectrically induced ringing is a significant factor in LiNbO₃ crystals, therefore the maximum recommended repetition rate for LiNbO₃ Pockels cells is about 1kHz.
