Abstract

A source, system and method for generating amplified stimulated emission is provided. The source (100) includes a pump source (102) for generating a pump light which is provided to a doped element, such as a doped fiber (112). Based on the pump light, the doped fiber, which may be a erbium doped fiber, generates the amplified stimulated emission. A coupler mechanism (114) provides the pump light to the doped fiber and transmits the amplified stimulated emission from the doped fiber. The coupler mechanism isolates the pump light and the amplified stimulated emission using phase conditions. A system is also provided including a source and a sensor, such as a fiber optic gyroscope. A method for generating the amplified stimulated emission is further provided.
