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.
This product is just the AO Modulator total unit, the green DPSS laser is not included. The AO Modulator will work with RF driver, which is included in the product.
