1064nm 200M Polarization-maintaining Acousto-optic Modulator

Product introduction

1064nm, 200MHz Polarization-maintaining AOM (acousto-optic modulator) is specially developed for the requirements of optical sensing. It has the advantages of small size, low power consumption, fast rise time, good modulation pulse shape (small overshoot), good pulse repeatability (small repetition period jitter), etc., and can Integrated packaging of the modulator and driver facilitates system integration and can be widely used in various optical fiber sensing systems that require pulse modulation, such as φ-OTDR, BOTDR, and OFDR.
Features
High damage threshold
Withstand high power

High extinction ratio

Applications
Optic sensing
Lasers and fast switching
