Embodiment Construction

[0121] refer to Figure 1a The exemplary and significantly simplified laser device 2 comprises a laser medium 10 , a resonator with an end mirror 12 and an opposing output coupling mirror 14 , and a pump light source 16 for generating pump light 18 . Population inversion can be produced in laser medium 10 by means of pump light 18 .

[0122] In the case of multiple laser systems, there are further components within the cavity, for example saturable absorbers in pulsed laser systems as Q-switches (for example made of cobalt spinel).

[0123] exist Figure 1b In the likewise significantly simplified example shown, the laser medium 10 is provided with a coating 15 , wherein the coating 15 is a partially reflective coating in order to enable outcoupling of light. Partially reflective coatings and end mirrors 12 are used as resonators. As known to the person skilled in the art, it is also possible to use a highly reflective coating as a resonator together with an end mirror in t...

Abstract

The invention discloses a laser medium for generating laser light, wherein the laser medium is in a solid state and wherein the laser medium comprises a light exit face through which the laser light exits from the laser medium during laser operation, wherein the light exit face has a boundary which is defined by at least one chamfer or groove. The invention further discloses a laser device having a laser medium of this kind, a pump source for introducing pumped light into the laser medium and a resonator for the interreflection of photons, wherein the resonator has an output mirror in particular formed by a partially reflective coating or an end mirror in particular formed by a highly reflective coating, and further discloses a method for producing the laser medium.

Description

technical field [0001] The invention relates to the field of solid-state laser media for lasing by stimulated emission of photons. Background technique [0002] Solid-state laser media, usually in the form of laser rods, are used as light-amplifying components in solid-state lasers. Usually, solid-state lasers are constructed in such a way that a laser rod is arranged in an optical resonator and irradiated with so-called pump light in order to excite higher energy levels. The resonator is used here to feed back the photons emitted during the transition from a higher energy level to a lower level, so that they can pass through the laser rod multiple times and increase the probability of induced, ie stimulated emission, occurring. [0003] A laser resonator can be realized, for example, by means of two mirrors placed opposite each other, one of which has a reflectivity close to 100 percent (end mirror) and the other has a lower reflectivity to allow a part of the laser light ...
