METHOD FOR OPTICAL PUMPING OF A LIGHT-AMPLIFYING MEDIUM AND OPTICAL PUMPING MODULE FOR IMPLEMENTING SAID METHOD

摘要

The invention concerns a method for optical pumping of a light-amplifying medium and an optical pumping module for implementing said method. The invention is characterised in that it consists in using at least a light source (40) for pumping the amplifying medium (24) and in enclosing said medium with a reflector (20) whereof the wall (22) reflects said diffused light; emitting the beam (18) directly coming from the source towards the wall so that it is subjected to the diffused reflections and placing the amplifying medium outside said beam so that it may be pumped only by the light diffused by the wall.
