Q1058C-SFxxL-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.
When the RF drive to the Q-switch is turned off, the built-up optical power in the laser is emitted as a short pulse.
AO Q-switches can operate in the Bragg regime with a single diffracted beam or in the Raman-Nath regime with multiple diffracted beams.
The specifications include an acoustic frequency of 24.00 or 27.12MHz, interaction material of Dense Flint, wavelength range of 1047nm to 1064nm, and an A/R coating of <0.5% per surface.
The Q-switch is conduction cooled, meaning it dissipates heat through the mounting surface.
