Q1025-TxxL-H AO Q-SWITCH
Description
Q-switches are intracavity devices used to generate very high peak power, short duration laser pulses. These are typically loss modulators operating on the zero order beam. The goal of a Q-switch is to diffract as much power from the zero order as possible to increase the cavity loss and extinguish the laser output. When the RF drive to the Q-switch is momentarily turned off, the optical power built up in the laser is emitted as a short pulse. The process may be repeated at rates in excess of 100KHz. Depending on the frequency and interaction length, AO Q-switches either operate in the Bragg regime, just like an AOM, with predominately a single diffracted beam or in the Raman-Nath regime with multiple diffracted beams.

Frequently Asked Questions
A Q-switch is used to generate high peak power, short duration laser pulses by diffracting power from the zero order beam.
AO Q-switches can operate in either the Bragg regime, with a single diffracted beam, or the Raman-Nath regime, with multiple diffracted beams.
The Q1025-TxxL-H AO Q-switch has a frequency range of 27.12MHz to 80.00MHz.
The active aperture size of the Q1025-TxxL-H AO Q-switch is 1.0mm or 1.5mm, depending on the model selection.
The recommended operating temperature range for the Q1025-TxxL-H AO Q-switch is -50ºC to +70ºC.
