Pumped solid-state laser, has pumping light reflected backwards and forwards through laser medium a given number of times for uniform distribution of pumping light

摘要

The laser has a pumping light source (4) providing pumping light (6) fed to a resonator (5) having a laser medium (1) with 2 opposing end faces (14,15) positioned between 2 mirrors (2,3) which are highly reflective for the pumping light over at least part of their surface, so that the pumping light is reflected backwards and forwards between the mirrors or the end faces of the laser medium a number of times.
