摘要： The invention relates to a CO2 laser which allows for rapid power modulation, particularly highly efficient Q-switching. The key concept is the sub-division of the resonator into a high-power branch, containing inter alia the active medium (1), and a low-power feedback branch (14), in which the power-sensitive beam-shaping elements, particularly the modulators, are arranged. This is made possible by a suitable arrangement of a polarisation beam splitter (5) and a lambda/4-phase shifter (2). The free adjustability of an angle phi between said two components permits the extremely flexible realisation of various operating modes, particularly optimisation of the feedback degree during pulse generation.

摘要： The invention relates to a method for boring holes having defined geometries into a large diameter region of 20 µm to 500 µm by means of laser radiation, preferably boring holes into fuel injection nozzles. The basic structure of said holes is bottle-like and characterized by three regions, a quasi-cylindrical fluid output region (4) ("bottle neck"), a transitional region (5) having an expansion of the hole diameter, and a quasi-cylindrical fluid inlet region (6) ("bottle body"). In the method described for boring such holes, it is typical to divide the overall boring process into two phases, a pre-boring phase and a molding boring phase, which particularly differ from one another in the shape of the focal acoustics of the laser radiation emitted. The focal acoustic variations necessary for attaining the desired hole shapes may preferably be attained by altering the wavelength and/or the beam quality count of the laser beam and altering the diameter or divergence of the beams at the site of the focusing element.
