    摘要： The invention relates to an optical arrangement having - a division element which divides an input beam consisting of a sequence of temporally equidistant light pulses into two spatially separate partial beams, - at least one optical element through which at least one of the partial beams propagates, and - at least one combination element which spatially superimposes the partial beams in an output beam. The problem addressed by the invention is that of showing a method for increasing the pulse energy of light pulses which is improved in comparison with the prior art. The invention solves this problem by virtue of the fact that the combination element superimposes a number of the temporally successive light pulses in a single light pulse in the output beam. The invention also relates to a method for increasing the pulse energy of light pulses.

    摘要： The invention relates to an optical resonator (1), comprising at least one optical element (2), which reflects or transmits laser radiation, preferably pulsed laser radiation. The aim of the invention is to create a practical possibility of coupling pulsed laser radiation out of or into a resonator (1). The invention achieves said aim in that the optical element (2) can be switched, wherein in a first switching position the laser radiation is reflected or transmitted in such a way that that the laser radiation circulates in the resonator (1), and wherein in a second switching position the laser radiation is coupled out of the resonator (1) or the laser radiation emitted by an external radiation source is coupled into the resonator (1).
