Compact Pockels Cells for Laser Q-switching - Electrical Optical ...

WebA 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 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 … WebFor “off Q-switching”, the laser is held off by the rotation of the polarization by the Pockels cell. In this case, the full half wave voltage may not always be required and it is recommended that the d.c. hold off voltage is increased until hold off is achieved at full optical pump power (with a little margin in hand).
