摘要:
The invention relates to a device for producing light pulses, comprising a pulsed light source (5) which emits a sequence of light pulses, an enhancement resonator (7) into which the light pulses emitted by the pulsed light source (5) are coupled, and a modulator (9) which couples at least one light pulse (10) circulating in the enhancement resonator (7) out of the enhancement resonator (7). The aim of the invention is to provide a device that is improved with respect to the prior art, by means of which device especially powerful light pulses can be produced. Said aim is achieved in that the pulsed light source (5) operates in a burst mode in such a manner that the pulsed light source (5) emits a sequence of pulse packets (6), which each comprise two or more consecutive light pulses. The invention further relates to a device for producing light pulses, comprising a pulsed light source (5) which emits a sequence of light pulses, an optical amplifying medium (17) which is optically pumped by the light pulses and produces useful radiation (21) as a result, and a multi-pass assembly (19) which ensures that the useful radiation (21) passes through the optical amplifying medium (17) several times. The pulsed light source (5) operates in a burst mode in such a manner that the pulsed light source (5) emits a sequence of pulse packets (6) that each comprise two or more consecutive light pulses.

The invention relates to an optical amplifier arrangement for amplifying ultra-short pulsed laser radiation comprising a mode-locked laser (1) and two or more optical amplifiers (3) arranged downstream of the laser (1) in the propagation direction of the laser radiation. Optical amplifier arrangements of this type are known in the prior art. Here the intention is to present an alternative to the known amplifier arrangements. The invention proposes arranging between the laser (1) and the optical amplifiers (3) at least one splitting element (2) which splits the pulsed laser radiation between a plurality of amplifier channels (4), wherein each amplifier channel (4) has at least one optical amplifier (3), and wherein at least one common combination element (5) is disposed downstream of the amplifier channels (4) and coherently superimposes the pulsed laser radiation amplified in the amplifier channels (4).

The present invention relates to a device (12) and to a method for amplifying light impulses (13). The device comprises a stretcher (15) stretching the light impulses over time, at least one amplifier (16) amplifying the stretched light impulses, and a compressor (17) compressing the stretched and amplified light impulses, wherein the amplifier (16) applies a non-linear phase generated by self-phase modulation to the stretched light impulses. In order to provide a device and a method for amplifying light impulses, by means of which light impulses having higher light impulse quality and light impulse peak power can be generated, the invention proposes that means for spectrally shaping the light impulses are disposed ahead of the amplifier (16) in the beam path, wherein the means for spectrally shaping the light impulses bring about a spectral trimming of the light impulses.
