Claim Text:
1. A short-pulse laser system for generating electromagnetic pulses comprising: a first resonator having a first beam path and a first resonator length; a second resonator having a second beam path and a second resonator length; and an amplification medium, wherein the amplification medium is arranged both in the first beam path of the first resonator so that it amplifies electromagnetic pulses in the first resonator and also in the second beam path of the second resonator so that it amplifies electromagnetic pulses in the second resonator, wherein the first resonator is so adapted that it supports precisely one first polarization state of the electromagnetic pulses and the second resonator is so adapted that it supports precisely one second polarization state, wherein the first and second polarization states are orthogonal to each other, wherein the first and second resonators are so adapted that the first and the second resonator lengths are variable relative to each other, and wherein a fiber amplifier is disposed in the first and/or in the second beam path.
