Low modulation frequency electro-optic switch
Pockels cell is a modulator about polarized light designed based on the Pockels effect. It is a key component in the laser cavity Q-switching, pulse selection and regenerative amplification system，and one of the best choices for intensity, phase and frequency modulation in laser processing and detection equipment.

| Goptica designed the Pockels cell with high repetition frequency, weak ringing, high damage threshold and low loss qualities based on foreign advanced technology. By designing a stable and reliable structure and electrode scheme, an effective thermal management scheme can be achieved, which can significantly reduce the impact of the external environment, improve the reliability of the device, and reduce the loss of high-frequency signals during transmission. |
Goptica have designed and developed Pockels cell including DKDP, BBO, RTP and KTP series,covering the frequency range from Hz to 60 MHz,and the performance reaches the international equivalent level. DKDP series use the transverse or longitudinal electro-optic effect, coverd with wavelenth range from 300nm to 1300 nm, the required voltage of the transverse can be controlled within 100 volts and the diameter of the longitudinal can reach 15 mm; BBO series used in the range of 250-1650 nm, the required voltage from 100 volts to thousands of volts; RTP series used in the range of 350-3500 nm, and its frequency can reach to 100 kHz, aperture up to 10 mm; KTP series selects the hydrothermal KTP to solve “spot nevus discoloration” phenomenon.
