AOM (Acousto-optic Modulator)
 |
It belongs to the high-speed acousto-optic pulse modulator which realizes the intensity modulation over the Laser according to the inputted pulse signal and gets corresponding digitally coded optical signal by inputting the digital signal of different codes and frequencies (TTL/ Analog) into the driving power supply of modulator. It is mainly used in such fields as laser text-image processing and laser digital communication. This product has such characteristics as quick modulation rate, small volume, high efficiency, high extinction ratio, easy coding and convenient use. |
