SOURCE, SYSTEM AND METHOD FOR GENERATING AMPLIFIED STIMULATED EMISSIONS

摘要

A source, system and method for generating amplified stimulated emissions (ASE) is provided. The source includes a pump source for generating a pump light which is provided to a doped element, such as a doped fiber. A grating is coupled to the output of the doped fiber for blocking any pump light which may have passed through the doped fiber. The grating may be a reflective Bragg grating which is designed to reflect the pump light. A double pass process may be implemented by positioning the grating to reflect the pump light back into the doped fiber. Some of the reflected pump light may also re-enter the pump source and lock the wavelength of the pump source. A system is also provided including a source for generating ASE and a sensor, such as a fiber optic gyroscope. A method for generating ASE is further provided.
