Free-space AO Modulator (Acousto-Optic Modulator)

M080-2G-LV1

• High efficiency (95% typical)

• Low drive power (0.3W typical)

• Compact

• Easy to align

Description

The M080-2G-LV1 is a compact AO Modulator specifically designed for extra-cavity modulation of Nd:YAG/Nd:YVO4 lasers where fast modulation is not critical.

Rise times down to 10μs are readily achievable, together with excellent efficiency, typically > 95% for a well-collimated laser beam.

The relatively wide field of view means that good efficiency is achieved for more divergent beams.
