Patent ID: 8750344

Claim:
A laser pump arrangement for producing elliptical pump geometries with ratios of pump light spot length to width of greater than 3:1 at the transition between a homogenizer and a laser medium that amplifies laser radiation, comprising at least one laser pump source having a plurality of emitters for generating partial pump beams, in particular laser diodes, for pumping the laser medium, one optical homogenizer for intermixing the partial pump beams in an intermixing axis by means of multiple reflections so that a complete or partial intermixing is achieved in the width of the elliptical beam profile, one coupling-in optical unit between laser pump source and homogenizer, wherein the coupling-in optical unit is designed and arranged such that the partial pump beams in a projection axis perpendicular to the intermixing axis are projected, in particular focused, directly onto or into the laser medium and homogenizer and laser medium are designed and arranged such that the pump beam emerging from the homogenizer is passed directly onto or into the laser medium with maintenance of divergence for the intermixing axis.
