Fibre-Q 111 AO Q-Switch

M111-2G-F2S

 

• 1μm fibre-coupled

• 111MHz drive frequency

• 25ns rise-time

 

Description

A fibre-coupled acousto-optic device for use as a Q-Switch or intensity controller with 1μm fibre lasers.

 

Utilising Gooch & Housego’s renowned crystal processing and coating expertise, coupled with superior design technologies, this device exhibits less than 3dB insertion loss while offering superb extinction ratio and rapid switching speeds, making it the perfect solution for Q-Switching fibre-lasers.

 

Even faster switching is available with model M175-2G-F2S and lower insertion loss with model M080-2G-F2S.
