Description

532nm Free Space AO Modulator (no fiber) is used for Switching 532nm CW Green Laser .  The 532nm AO Modulator is a laser device which can be used for controlling the transmitted power of a 532nm green CW laser beam with the electrical drive signal. The drive signal can be TTL or modulation.  This AO Modulator is also called Q Switch. It uses the TTL Signal to turn on/off the 532 CW laser.

There are 2 types for the AO Modulators, free space and fiber coupled. The 532nm CW laser goes directly into the AO Modulator , no fibers needed.
