| 摘要 |
The invention concerns a laser device with a multiplicity of individual lasers located in an active zone (2) and delimited by outer surfaces (9 to 13) including front and rear surfaces (9, 10) running at right angles to the laser-light (8) output direction and side, bottom and top surfaces (11, 12, 13) running parallel to the laser-light output direction. Several, preferably all, of the surfaces (9 to 13) of the laser device (1) are at least approximately completely covered by an absorbent film (14 to 17) that contains a material which reduces the reflection of and/or absorbs the laser light and/or has a refractive index which matches that of the active zone.
