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. |
