摘要： Systems and methods are disclosed for shaping a laser beam for interaction with a film in which the laser beam travels along a beam path and defines a short-axis and a long-axis. In one aspect, the system may include a first short-axis element having an edge positioned at a distance, d1, along the beam path from the film and a second short-axis element having an edge positioned at a distance, d2, along the beam path from the film, with d2

摘要： The disclosure relates to a light beam intensity non-uniformity correction device that includes an optical element having a light entrance face with an antireflective property. According to the invention the antireflective property is locally amended in order to enhance light beam intensity uniformity. The disclosure further relates to a method for amending intensity distribution of a light beam in an optical system having one or more optical elements, where the method includes: a) assembling the optical system with the one or more optical elements arranged in predetermined positions, b) measuring intensity distribution, c) calculating locally required increase or decrease in absorption and/or reflection of one of the optical elements to amend measured intensity distribution into a predetermined intensity distribution, d) removing the optical element from the optical system, e) locally amending absorption and/or reflection of the one of the optical elements according to the calculation, f) installing the optical element in the predetermined position in the optical system.

摘要： An optical system for shaping an incoming beam having a divergence with an angular distribution at least in a first direction comprises at least one angle selective optical element for clipping the angular distribution in the at least first direction. The approach according to the present invention bases on using an angle-selective device operated by the principle of total internal reflection to reduce divergence of the incoming beam, in contrast to a spatially-selective device as for example a field-stop or slit. The method according to the present invention has the advantage that no physical sharp edges have to be exposed at high energy densities. Thus, thermal impact and demands on the optical elements to withstand a high power laser beam are significantly reduced.
