| description | The invention relates to the field of laser technology and can be used for more efficient optical pumping of laser media in laser generators and amplifiers. The invention can be used for the efficient optical pumping of practically all types of lasers, provided that the absorption profile of the pumped medium is sufficiently broadband. The invention discloses a method and device for combining at least two laser beams of different wavelengths, the polarization states of which are substantially orthogonal, into an exit beam by using a polarizing beamsplitter which spatially combines two beams in mutually orthogonal polarization states, and then changing the polarization state of one of the beams relative to the other using a spectrally selective polarization filter such that the polarization state of the exit beam becomes substantially identical for all of the wavelengths of the exit beam, thus permitting the subsequent combining thereof with another beam. |
