ABSTRACT:
The aim is to provide a new power laser configuration enabling the delivery of a beam of high spatial quality with an optimum efficiency of extraction of energy. It can be applied, more particularly, to Q-switch solid-state lasers, in doing away with recourse to specific elements for compensation of aberrations. The structure of emission of a power pulsed laser signal, of the type comprising, firstly, an oscillator stage with low-level output beam and, secondly, a power amplifier stage, is characterized in that the power amplifier stage is formed by a laser amplifier that produces a pump beam cooperating with distinct means for energy transfer without phase transfer from said pump beam towards said low-level beam coming from the oscillator.
