Chinese Acousto-Optic Modulator
2026-02-04
The key parameter of AOM is the rise/fall time, which defines the achievable “speed” or amplitude modulation bandwidth of the modulation. The rise/fall time is proportional to the beam diameter within the modulator. Therefore, in order to obtain a fast rise time, it is necessary to control the diameter of the incident laser beam.
AOM can be used as a shutter (to cycle switch according to the set frequency) or as a variable attenuator (to dynamically control the intensity of transmitted laser beam).
ModuOptik has developed a series of free-space (up to 24 channels in a single channel) and fiber-coupled (PM fiber and non-PM fiber) AOM with a frequency range of up to 300 MHz and a rise time as low as 6 ns, wavelength cover from UV to far infrared(266, 343, 355, 532, 800, 1045, 1030, 1064, 1553, 9300, 10600 etc). AOM selects AO materials with excellent quality (Fused quartz, Quartz crystal, Ge crystal, etc.), which can be designed into shear and longitudinal wave mode according to needs. High quality optical polishing, anti-reflective coatings with low reflection and high damage threshold, reliable welding techniques, and novel acoustic management and optical mechanical design techniques enable excellent thermal management, maintaining excellent beam quality and high transmittance.
