摘要： The invention discloses a high power laser diode comprising a plurality of laser light emitters (2) and a plurality of light collimating means (33), wherein each of the laser light emitters (2) defines, in a direction perpendicular to a direction of propagation (32) of an output laser beam, a fast axis (y) and a slow axis (x), and wherein each of the light collimating means is associated with a laser light emitter and configured for collimating the output laser beam at least in a fast axis (y) direction. In order to enable a simple and cost-efficient assembly of the diode laser with collimating means, having a layered structure consisting of a plurality of plane-parallel substrates. For this purpose, the diode laser comprises planar substrate means (10, 30) which serves to precisely define a distance between a respective laser light emitter (2) and an associated light collimating means to the order of one or several millimetres and to support the collimating means (33) such that the optical axis of said laser light emitters are parallel to each other and for defining a precise location of emitters on the planar substrate (10), preferably at predetermined distance in fast axis direction between said laser light emitters. The collimating means is an array or multiple single of micro-optical lenses having a rear side which is bonded to the upper surface of the planar spacer means. The submounts of the light emitters (2) are mounted to the planar substrate means (10, 30) and to a heatsink (6).

摘要： An apparatus for shaping the output beam of a strip of lasers, or an array of such strips, comprising a first reflective member including at least a first reflective element for deflecting a first portion of the output beam in a first direction oriented at a first angle in the slow axis direction and at a second angle in the fast axis direction, and at least a second reflective member including at least a first reflective element for deflecting the first output beam portion from the first direction to a second direction in the Z axis. The output beam is thus shaped to define at least two beams comprising at least the first portion and a remainder of the output beam which is propagated along the Z axis without deflection by any reflective member, with the first portion of the output beam being oriented approximately parallel to the un-deflected remainder.

摘要： An optical arrangement is provided for balancing the beam of one or more high-power diode lasers (HP-DL) arranged one above another. The beam, which is known to diverge very differently in the direction of the pn junction and perpendicular to the pn junction of the emitters of an HP-DL arranged in a row is imaged at a point with high power density and high beam quality the arrangement. Present for this purpose are optical devices which spread out the radiation in a mutually offset fashion in the direction of the pn junction while the radiation is superimposed perpendicular to the pn junction.

摘要： A high-power diode laser and a method for mounting same are described. Predetermined breaking locations in the laser bar are provided which, during cooling after the laser bar has been soldered to a heat sink having a smaller thermal expansion coefficient, lead to breakage at defined locations between the single laser diodes of the laser bar. As a result of the physical division of the laser bar, it is possible to use a solder which has low ductility (hard solder) at room temperature, since destruction of the single laser diodes of the laser bar as a result of mechanical stresses can be ruled out.
