Abstract: In a laser pump arrangement for a laser medium that amplifies a laser beam, comprising at least one laser pump source (1″) with a plurality of emitters for generating partial pumping streams (TPS1″, TPS2″), the partial pumping streams (TPS1″, TPS2″) are led through a coupling optic to a homogenizer (3″) and then are thoroughly mixed in one axis through multiple reflections. In the process, the homogenizer (3″) and the laser medium are designed and disposed such that the pump stream exiting the homogenizer (3″) is led directly onto or into the laser medium while maintaining divergence in the mixing axis (DA), wherein the partial pumping streams (TPS1″, TPS2″) are projected, in particular focused, directly onto or into the laser medium in a projection axis (PA) that is perpendicular to the mixing axis (DA).

Abstract: The invention relates to a highly repetitive laser system operating according to the reproducible amplifier principle. Said system comprises at least one amplified laser medium, a laser resonator provided with at least one resonator mirror and at least one modulator and a pump source, in particular, a laser diode source, which is used to pump the laser medium. The highly repetitive laser system is compact by virtue of the fact that a pulse extensor, having a highly dispersive effect as a result of the structure or material thereof, is integrated into the laser resonator.

Abstract: A pulse train generator for generating laser pulses comprises a laser setup with a cavity, an electro-optic switch for switching the pulses in and out from the cavity. The electro-optic switch and a control element are designed and connected for switching out laser pulses with a first repetition rate thereby forming a sequence of laser pulses. Said sequence of laser pulses is repeated with a second repetition rate, thereby forming a repeating sequence of laser pulses. A potential function with at least two steps or a switch setup with two electro-optic modulators are used to operate the setup with the second repetition rate.

Abstract: In a laser system with optical parametric amplifier (8), a laser source (1) for generating seed pulses, and a regenerative amplifier (2) for generating pump pulses, the seed pulses of laser source (1) are coupled, both into the regenerative amplifier (2) and into the optical parametric amplifier (8). Moreover, the auxiliary beam (HS) generated in the optical parametric amplifier (8) is passed through an arrangement with positive dispersion (14) so that, in view of the inverted chirp of the auxiliary beam (HS), the pulses are recompressed. A pulse stretcher can also be used as an arrangement with positive dispersion for recompression of the auxiliary beam (HS), so that a further component can be omitted.
