| 英文摘要 | The present invention relates to a laser device comprising at least one large area VCSEL (101) and at least one optical feedback element (201, 301) providing an angular-selective feedback for laser radiation emitted from the laser. The angular-selective feedback is higher for at least one portion of laser radiation emitted at angles ? > 0 to the optical axis (601) of the laser than for laser radiation emitted on said optical axis (601). The invention also refers to a method of stabilizing a laser emission of a large area VCSEL in a desired angular distribution (501, 502). With the proposed device and method, the intensity distribution of a large area VCSEL can be stabilized in a desired shape, for example a ring shape. |
