Abstract: The present invention relates to a stable optical cavity, in which an obstacle is formed or arranged on the optical axis in the form of a through-opening in one of the mirrors or of an input- or output-coupling element, in order to enable a direct geometric access to the optical axis. The mirrors of the cavity are arranged such that a degeneracy of a plurality of transverse eigenmodes of the cavity occurs without an obstacle, by the combination of which an intensity minimum is obtained in the cavity with an obstacle at the position of the through-opening or of the input- or output-coupling element. With this configuration an optical cavity of high finesse which has a position of maximum intensity on the optical axis can be realized.

Abstract: 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 θ>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.

Abstract: A laser assembly and method of operating the assembly are described in which a pump beam is directed through an end-pumped solid-state laser gain medium four or more times. The pump beam is directed at a slight angle through a first end of the medium, reflects off the inner surface of the second, opposite end (to form a “V”), and then reflected by an external or integrated mirror back through the first end and off the inner surface of the opposite end again (back through the “V”).
