Fiber-Coupled Acousto-Optic Modulators
Product description:
Fiber-coupled acousto-optic modulator (FCAOM) is based on the principle of body wave acousto-optic interaction and has the ability of optical pulse amplitude modulation and optical frequency shift. The rise time of the optical pulse output of the modulator represents the modulation speed which determines the response speed and available bandwidth of the system. Compared with free-space acousto-optic devices, FCAOM has the advantages of convenient to use, easy integration and high reliability with optical fiber coupling. It is widely used in fiber sensing system, fiber laser and other fields.
CASTECH can customize FCAOM with corresponding parameter according to customer requirements. The optical fiber terminal of FCAOM could be configured with FC / APC or other connectors as required.
Applications:
●Laser marking
●Lithography
●Material processsing
●Medical surgery
●Micromachining
