Abstract
For the generation of amplified, phase-coherent light pulses, a sequence of phase-coherent, equidistant input light pulses (21) is coupled into a resonator device (1) with at least two resonator mirrors (11, 14), forming a light path (10) with a predetermined resonator length, in such a way that the coupled in input light pulses in the resonator device are linearly superimposed in succession to form at least one circulating light pulse, whereby the circulating light pulse is coupled out of the resonator device as an output light pulse (31) as soon as the circulating light pulse has reached a preset minimum level of energy.

Method for generating phase-coherent light pulses in which a sequence of phase-coherent, equidistant input light pulses is coupled into a resonator device with at least two resonator mirrors, forming a light path with a predetermined resonator length, in such a way that the coupled-in input light pulses in the resonator device are linearly superimposed in succession to form at least one circulating light pulse, whereby the circulating light pulse is coupled out of the resonator device as an output light pulse after the circulating light pulse has reached a preset minimum level of energy.
Resonator device for light pulse amplification consisting of:
- at least two resonator mirrors forming a light path with a preset optical resonator length, whereby the first resonator mirror forms an input coupling mirror for phase-coherent input light pulses and the light path is free of amplification media, and
- a modulator element for coupling at least one output light pulse out of the light path, whereby each output light pulse represents a linear superposition of a plurality of input light pulses.
