Abstract:
1. A device for amplification and/or transport of electromagnetic radiation, having a radiation source for production of the electromagnetic radiation, as well as an amplifier for amplification or a medium for transport of the produced electromagnetic radiation, respectively, wherein the electromagnetic radiation that propagates in the amplifier or medium, respectively, is polarized, wherein the linear component of the polarization is substantially zero, wherein the electromagnetic radiation propagating in the amplifier or in the medium, respectively, is elliptically polarized, wherein the polarization state of the elliptically polarized electromagnetic radiation is determined by the position r>0.9, on the one hand, r denoting the degree of polarization, and by |ε|>30°, |ε|>35°, or |ε|>40°, on the other hand, ε denoting the ellipticity, on the Poincaré sphere.
