Architecture of Pumping Laser and laser Guide star system with Raman Fiber Amplifier Remote Telescopes

摘要

A Pumping System for the distance of a Raman Fiber Amplifier, which comprises a laser Pumping located at a distance of Raman Fiber Amplifier, a laser Head and one or more Optical Fibers for optically coupling the Light Pumping High Power from the l Aser Pumping away with respect to the Raman Fiber Amplifier.The Amplified laser Light Field, where the laser pumping, which is intended to produce a high power laser Light of a Predetermined Wavelength Pumping.Includes a First Fiber laser which emits light with a Predetermined Wavelength of Pumping Laser and a (Second) or two (Third) (n) laser that emits Light of a Wavelength of Pumping is less than the Wavelength of Pumping SetMultiply the light with the light from the first laser in an optical fiber Raman gain that provides a Wavelength Pumping with the default Way of converting Light of the second (and optionally Third) laser Light with a Wavelength of Pumping pre Determined.
