摘要： In order to improve a laser amplification system, comprising a solid-state body having a laser-active medium, a pumping radiation source for generating a pumping radiation field which passes through the solid-state body several times, an optical pumping radiation imaging means which is arranged between the pumping radiation source and the solid-state body and focuses a leg of the pumping radiation field entering the solid-state body onto the solid-state body and at least one optical refocusing means which focuses a leg of the pumping radiation field exiting from the solid-state body onto the solid-state body again in the form of a leg entering the solid-state body and different to the outgoing leg, in such a manner that as high a pumping radiation power density as possible can be generated in the solid-state body with as little resources as possible it is suggested that the optical refocusing means reshape the leg exiting from the solid-state body into an intermediately collimated leg and reshape the intermediately collimated leg again into the leg entering the solid-state body again and focused onto it.

摘要： The invention relates to a laser amplifier system consisting of a solid body, which comprises a laser-active medium, of a pumping radiation source for generating a pumping radiation field, which repeatedly permeates the solid body, and of a focusing system. Said focusing system generates a number of different branches of the pumping radiation field that enter the solid body and converts at least one branch emerging from the solid body into one of the branches which enter the solid body and which are different from the emerging branch. The aim of the invention is to improve a laser amplifier system of the aforementioned type in order to be able to generate the highest possible pumping power density in the solid body while requiring the smallest possible amount of complexity. To this end, the focusing system comprises at least one deviating unit which converts, by deviating the radiation field with regard to a single plane of symmetry, at least two first partial branches formed from at least two different branches of the pumping radiation field emerging from the solid into at least two corresponding second partial branches which locally extend in a manner that is separate from the first partial branches and of which at least two branches entering the solid body are formed.

摘要： The invention relates to a laser amplifier system consisting of a solid body, which comprises a laser-active medium, of an excitation source for producing an excited state of the laser-active medium, and of an amplifier radiation field, which repeatedly permeates the solid body and out of which a laser beam can be decoupled. The aim of the invention is to improve a laser-amplifier system of this type so that the highest number of passages of the amplifier radiation field through the solid body can be attained using optical means that are provided in the most simple possible form. To this end, the invention provides radiation field guiding optics which enable the amplifier radiation field to enter the solid body in the form of a number of incident branches with locally different trajectories, and which enable the amplifier radiation field to exit the solid body in the form of at least one emerging branch with a trajectory that differs locally from those of the incident branches. In addition, the radiation field guiding optics comprise at least one deviating unit which, out of at least one of the branches emerging from the solid body, forms a branch which enters the solid body and which has a trajectory that differs locally from that of said emerging branch.

摘要： A laser amplifying system is provided having a solid body arranged in a laser radiation field and including a laser active material that is pumped with a pumping light source. The solid body has a cooling surface and transfers heat created therein to a solid cooling element via the cooling surface. In this manner, a temperature gradient results in the solid body in a direction towards the cooling surface. The solid cooling element forms a carrier for the solid body. The laser radiation field propagates approximately parallel to the temperature gradient in the solid body. By enabling heat to be transferred to the solid cooling element via the cooling surface, this structure enables the solid body to be pumped at a high pumping power. Further, since the laser radiation field propagates approximately parallel to the temperature gradient in the solid body, the radiation field sees the same temperature gradient in all cross-sectional areas. Thus, the temperature gradient does not lead to an adverse effect on the beam quality of the laser radiation field at high pumping power.

摘要： In order to improve a solid-state laser, in particular a solid-state disc laser, comprising a resonator (40) that defines a resonator radiation field (30) and at least one solid-state disc (12) with the resonator radiation field (30) passing through it, in such a manner that the thermal lens effect can be at least substantially compensated, it is proposed that in reflection the resonator radiation field (30) strikes at least one first adaptive mirror unit (50, 70), with which a distortion of the resonator radiation field (30) as a result of a thermal lens effect of the at least one solid-state disc (12) can be substantially compensated. An adaptive mirror unit (50) can be configured by a heated (58a, 58b) glass sheet (54) with an HR layer (52), for example, or by a pressure-induced deformation by means a fluid (78) in a space (76), which is enclosed with the mirror (72, 74).

摘要： A laser for generating pulsed laser radiation. An element is arranged in the resonator to generate laser radiation having the first wavelength by frequency conversion of the primary radiation. The resonator is switchable into a first state in which it is open to the primary radiation, and a second state in which it is closed to the primary radiation, and is open to laser radiation of the first wavelength in both states. A control unit switches the resonator from the first to the second state so that the primary radiation begins to oscillate and the pulse generation by frequency conversion begins, switches the resonator from the second to the first state, whereby primary radiation is coupled out from the resonator. It is possible to set the duration between both steps and/or the coupling-out behavior of the resonator to adjust the pulse duration via the control unit.
