LASER OSCILLATOR

摘要

A single mode semiconductor laser includes a first optical resonator, which is formed by a total reflection surface and a partial reflection surface. Light emitted from the partial reflection surface of the single mode semiconductor laser enters a fiber Bragg grating, which includes a diffraction grating formed therein. The diffraction grating forms a second optical resonator in combination with the total reflection surface of the single mode semiconductor laser. A fiber amplifier amplifies a laser beam emitted from the fiber Bragg grating.
