Q-Switches

A Q-Switch is a special modulator which introduces high repetition rate losses inside a laser cavity (typ 1 to 100 KHz).

They are designed for minimum insertion loss and to be able to withdtand very high laser powers. In normal use an RF signal is applied to diffract a portion of the laser cavity flux out of the cavity. This increases the cavity losses ans prevents from oscillation.

When the RF signal is switched off, the cavity losses decrease rapidly and an intense laser pulse evolves.
