    Abstract: The invention relates to a laser amplifier system with time-proportional frequency modulation comprising a laser oscillator, which generates ultrashort pulses, a passive dispersive optical waveguide, which temporally stretches these ultrashort pulses, and at least one double-sheathed fiber, which is doped with active ions and which is provided for amplifying these pulses. The laser amplifier system is also equipped with an optical compressor, which comprises dispersive components and which compresses the stretched pulses that are received from the amplifying double-sheathed fiber. According to the invention, the amplifying double-sheathed fiber is doped with active ions in the core and in the first sheath layer, whereby the dopant concentration of the core is greater that that of the first sheath layer and, in the core, is constant or increases over the length of the fiber in a direction of propagation of the light pulse. In order to form a variable pulse width, the optical compressor is constructed of gratings that are arranged on a metal support, whereby the cooled gratings are designed such that they can displaced with defined intervals in a computer-controlled manner. The inventive laser amplifier system also comprises a modulator which is provided for adjusting a variable repetition rate and which is arranged between the laser oscillator and the compressor. In one embodiment, passive dispersive optical waveguides and amplifying double-sheathed fibers are integrated in one fiber.

    Abstract: Costly devices, e.g. accelerators, are required in order to examine the inner structure of materials, or until now there has been no available method. The present inventive method enables a material sample to be radiographed under a vacuum using a proton beam which is produced by exposing a film of solid matter, also under a vacuum, to a laser beam. The exposed region of the material sample is imaged by a proton detector which is arranged in the radiation path of the proton beam, behind the material sample. Information about the plasma density, the plasma temperature, the degree of the plasma charge and the spatial structure of certain plasma regions is obtained by radiographing plasmas using laser-produced protons. Furthermore, temporal courses in the plasma can be efficiently determined. Image information can be obtained for regions which are not accessible using conventional image-producing methods.

    Abstract: The invention relates to a method for detecting displacements of individual brain areas and to the representation thereof on a display for guaranteeing optimal planning of an operation, said displacements being caused by tumour formation. According to the invention, a displacement vector is detected for each brain area which was situated at a defined location in the initial position where a tumour is located now. Said displacement vector defines the displacement of a brain area in the direction and the amount thereof, whereby said displacement is caused by tumour growth. Said vector is detected by means of two parameters (b and c) which can be derived from the size and the kind of the tumour. The displacement vectors are numerically calculated according to the formula ur=cr + br after the two parameters have been detected. The image of the tumour as well as the detected displacements are subsequently inserted into a stereotactic atlas. The brain areas are displayed at the actual locations in the thus obtain image. Improved planning for carrying out operations can thus be guaranteed by means of said representation.

The problem addressed by the present invention is that of devising a method and a device for producing and detecting a Raman spectrum of a medium under investigation, whereby the Raman spectrum of a medium that is under investigation can be examined with a high degree of sensitivity while requiring relatively little equipment.

    Abstract: The aim of the invention is to specify a UV photodetector that has high sensitivity and a low dark current. According to the invention, the fingers (18) of the first electrode structure (14) and the fingers (24) of the second electrode structure (20) are formed by a cover layer (30) made of a second semiconducting material, wherein the cover layer (30) is arranged on the absorber layer (12) and directly contacts the absorber layer (12) in the region of the fingers (18, 24), and the first semiconducting material and the second semiconducting material are designed in such a way that a two-dimensional electron gas (2DEG) is formed at the boundary layer between the absorber layer (12) and the cover layer (30) in the region of the fingers (18, 24). The design of the fingers (18, 24) of the cover layer (30) can be achieved by the removal of the 2DEG in the region between the fingers by etching. Alternatively, electron mobility at the boundary layer between the cover layer (30) and the absorber layer (12) outside of the regions forming the fingers (18, 24) can be sufficiently reduced by ion implantation.
