Illumination structure of a laser rod with delocalized optical sources.

摘要

The field of the invention is that of the power lasers pumped by a coherent optical sources, such as laser diodes. / p & & p & the objective of the invention is to provide a structure of the illumination of a laser bar allowing both a good evacuation of heat released by the coherent optical sources of pumping, and a good homogeneity of the pumping operations of the bar. / p & & p & the structure is characterized in that the optical sources 12 of at least one set of optical sources are disposed on a same support engine 14, and in that said structure includes a reflecting means 10, to return towards the bar 17 of the illumination beam of the set of optical sources delocalized.
