Longitudinally pumped solid-state laser and method for longitudinal pumping lasers

摘要

A method for longitudinal pumping lasers, in which at least two diode lasers (11, 12) emitted pump radiation (14) in a laser active medium (13) is coupled to the longitudinally, in order to generate a laser beam or to intensify, wherein for the pump radiation (14) at least two different wavelengths are used, characterized in that a dichroic mirror for coupling the pump beam of a lead is used, the wavelengths of the pump radiation (14) for coupling a by a dichroic mirror suitable distance, and wherein the laser-active medium (13) in at least two different laser levels (n3, n4) at the same time, is excited directly and indirectly.
