Eo Q-Switch (Pockels Cell)

A Pockels cell alters the polarization state of light passing through it when an applied voltage induces birefringence changes in an electro-optic crystal such as DKDP (KD*P) and BBO. When used in conjunction with polarizers, these cells can function as optical switches, or laser Q-switches. Frequently, Q-switches are employed in laser cavities for the purpose of shortening the output pulse, resulting in a light beam with enhanced peak intensity. In order to provide the device best suited to your purpose, we offer the DKDP (KD*P) series and LiNbO3 series Pockels cell.

You can operate the cell with either a pull-up voltage or a pulldown voltage. Changing the polarity will only change the direction of the phase rotation. In other words, the pull-down voltage Q-switch use ª-/4-voltage pulses on the Pockels cell and the pull-up voltage Q-switch use ª-/2-voltage pulses on the Pockels cell. You should not, however, operate the cell with a constant applied voltage potential between the terminals, or a duty cycle greater than ~ 2%.
