Abstract:
A solid-state laser, comprising:at least two pump light sources generating polarized laser light of different polarities, said pump light sources including a plurality of laser diodes, a multi-mirror arrangement comprising a stepped mirror arrangement arranged behind said laser diodes and generating a high luminous density of the laser light by superimposing the laser light of the individual laser diodes, and a first lens arrangement following said multi-mirror arrangement; single waveguides associated with said pump light sources into which the laser light of high luminous density leaving said pump light sources is coupled by said first lens arrangement; a polarization-dependent and semi-translucent mirror following said light sources for further increasing the luminous density by combining the laser light transported by said single waveguides; a second lens arrangement arranged behind said polarization-dependent and semi-translucent mirror; and an optical laser resonator having a laser crystal following said second lens arrangement, the laser light combined by said polarization-dependent and semi-translucent mirror being coupled into at least one of said laser crystal of the laser resonator and a further single waveguide by said second lens arrangement.
