摘要： The proposal is for a laser amplifier system with a laser-active solid body material pumped by pumped light sources, in which one or more pump beams are guided with the aid of mirrors or other optical auxiliaries in such a way that each individual pump beam is focussed at various points on the solid body material, where the latter is in the form of a coherent or separate solid body shaped in such a way that the pump beam is absorbed in the focal regions and only there, whereby the latter are optically pumped, and the laser beam is deflected and guided in such a way that it irradiates all said focal points and is thus amplified. This provides a laser amplification system in which the system properties are simultaneously optimised and in addition permits a compact construction and is designed to permit economical mass production.

摘要： Apparatus using dye lasers for the production of pulsed light at a desired wavelength wherein the dye cells (4, 5) are fed with a weak beam of a narrow desired wavelength and pumped at another wavelength, thus producing an amplified output at the desired wavelength, the apparatus having a special aptitude in certain medical treatments. A metal vapour laser is employed using copper and gold active media in spatially separated regions, with the strong copper output at 511 nm and 578 nm being passed through a wavelength selective mirror (1) to pump two dye cells (4, 5) which are locked to the weaker 628 nm output obtained from the gold vapour discharge.

摘要： An arrangement is disclosed for geometrically shaping a radiation field, in particular the radiation field of a diode laser array (14) which propagates in the z direction and has a radiation cross-section which is larger in a direction defined as the x direction perpendicular to the z direction than in a direction defined as the y direction, which is perpendicular to the first, and has a lower radiation quality in said direction. X, y and z form a coordinate system. The radiation is grouped into radiation fractions in the x direction and the radiation fractions are reoriented as regards their radiation cross-sections. The arrangement has at least two reflective elements (22, 23) and is characterised in that each reflective element has a pair of reflection surfaces at approximately or exactly 90 DEG to each other. This opening angle is oriented against the direction of propagation. The line at which the reflection surfaces intersect is oriented at approximately below 45 DEG to the x direction.

摘要： The invention relates to laser systems of the type comprising optical fibre amplifiers. A laser system comprises a first laser (1) and a second laser (2). The second laser (2) is pumped at a first wavelength μ1 and caused to lase at a second wavelength μ2. The first laser (1) has absorption bands at μ1 and μ2. The output μ2 of laser (2) and the remnant pump at μ1 are coupled and both are used to pump the first laser (1), thus causing laser (1) to lase at a third wavelength μ3.
