Free-space Acousto-Optic Modulators
Product description:
Acousto-optic modulation is an external modulation technology, which can control the intensity of laser beam, and its speed is much faster than that of mechanical shutter. Acousto-optic modulator (AOM) can be used in laser modulation, laser graphic processing, laser digital communication and other fields. It has the characteristics of fast modulation speed, compact size, high modulation efficiency, high extinction ratio, easy coding and convenient to use.
CASTECH offers customized services that optimize the modulation scheme according to the demanding speed, wavelength, power, beam diameter and extinction ratio for our customers.
Applications:
●Laser marking
●Lithography
●Material processsing
●Medical surgery
●Micromachining
