  • Pump radiation arrangement and method for pumping a laser-active medium
    Patent number: 9331451
    Abstract: The disclosure relates to a pump radiation arrangement comprising: a pump radiation source for producing pump radiation, a means for stabilizing the wavelength of the pump radiation source and a laser-active medium through which the pump radiation passes in a bidirectional manner. The pump radiation arrangement also has a retro-reflector for reflecting pump radiation which is not absorbed by the laser-active medium back to the pump radiation source and a wavelength-selective element for preventing a wavelength destabilization of the pump radiation source by filtering out undesirable spectral portions of pump radiation which is not absorbed by the laser-active medium. The invention also relates to an associated method for pumping a laser-active medium.
