Optical fiber laser for optoelectronic industry in field of optician sensing and in treatment and processing of materials, consists of network of Bragg recorded in fiber photosensitive and active optics system

摘要

The optical fiber laser consists of a network of Bragg recorded in a fiber photosensitive and active optics, a system for excitation of the active material, an element generating transducer of vibrations and a coupling between the transducer and the optical fiber. The pressed emission of the laser with distributed feedback is obtained to spread an elastic wave along the bragg network. The elastic wave is generated by the excitation of the transducer and transmitted to the fiber.
