摘要： The use of reflecting surfaces that are inclined towards one another enables the multiple reflection of a beam path to be achieved in a laser structure. This permits the realization of compact laser assemblies. The introduction of beam-influencing media between the reflective surfaces or the configuration of said reflective surfaces from or using media of this type allows the use of the multiple reflection for influencing parameters of the radiation or radiation field.

摘要： In a laser arrangement comprising at least one laser medium for producing a laser emission, a laser resonator having a beam path with a length of at least 20 cm and with at least one end mirror, the beam path within the laser resonator is formed at least partly by free-beam optics. A resonator element arranged in the beam path has at least two optical surfaces as surfaces interacting with the radiation led via the beam path, these optical surfaces being rigidly connected to one another and being adjustable together in the beam path in such a way that, on tilting by an angle error, they achieve substantially the same effect on the guidance of the beam path but with opposite sign, so that mutual compensation of tilt errors takes place.

摘要： The optical component designed preferably for use in a laser cavity for the generation of a pulsed laser beam, especially a mode-coupled beam in the microsecond to the femtosecond range, contains a coating ensemble that acts as a saturable absorber, contains several layers, and is wave-coupled and “etalon-free,” having at least one saturable absorptive layer. The sequence of layers in the coating ensemble can be laid out such that for an incident cavity beam a negative dispersion of the group velocity (negative group delay dispersion and negative group velocity dispersion) also results. In the optical component which acts among other things as a saturable absorber and can be used as such, separate, individual, discrete optical elements need not be assembled in a sandwich-type construction with minimization. Instead, the optical component is a coating ensemble in which each individual layer, together with the remainder of the ensemble, contributes to the phase-coupled overall behavior of the incident beam. One or more layers which exhibit the saturable absorptive properties may be positioned in this ensemble, naturally allowing for phase-constant relations, such that an optimal, in this case a saturable absorptive, effect can be achieved.

摘要： 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.

摘要： The invention relates to a method and devices for pumping a laser, and to a laser element, which is specially designed therefor and which contains laser-active material. In order to prevent the laser-active material from being subjected to excessive thermal stress, particularly during a thin disk setup, an, in essence, elongated pumped light spot is irradiated onto a laser medium placed on a temperature sink whereby producing a two-dimensional heat flow. This achieves an improved cooling and a reduction of the maximum temperature.
