Fibre-Q 175 AO Q-Switch

M175-2G-F2S

 

• 1μm fibre-coupled

• 175MHz drive frequency

• 10ns rise-time

 

Description

A fibre-coupled acousto-optic device for use as a Q-Switch or high bandwidth modulator with 1μm fibre lasers.

 

In a compact, conduction cooled package, with fibres ready for splicing, this modulator exhibits an incredibly fast 10ns rise-time, making it ideal for short pulse generation. It may be used intra-cavity as a Q-Switch, or extra-cavity as a high bandwidth (50MHz) analogue/digital modulator.

 

Refer to model M080-2G-F2S for a lower insertion loss option.
