Fiber lasers with shared pump

摘要

A plurality of fiber lasers or amplifiers which share a common pump source. Cost and efficiency improvement of waveguide fiber telecommunications systems are made possible by routing pump laser power through a 1xN coupler to supply pump light to desired combinations of optical fiber lasers or amplifiers. The design is readily adapted to the use of modules, for example laser modules which have a port for receiving pump light and a port for receiving a wavelength selecting module.
