Raman Lasers - an overview | ScienceDirect Topics

Raman lasers have been operated in the infrared region extending from 1.1–1.6 μm, a region useful for optical fiber communications, using a Nd:YAG laser as a pump [50]. When a Raman laser is pumped by a train of pump pulses, each Raman pulse after one round trip should be properly synchronized with one of the succeeding pump pulses.
