An optically pumped miniature - laser resonator, a method for the production and laser with such a resonator.

摘要

The mini cavity comprises a solid emitter (1b) of a parallelepiped, electrically insulating, provided with two parallel lateral faces polished (6, 8), of a monocrystalline substrate (2) and a plurality of monocrystalline layers grown epitaxially on the substrate and having, in directions parallel to said faces a hardness equal to that of the substrate, one of the layers constituting a guide layer (4) adapted to guide the light emitted by the transmitter and the pumping light and another layer (12) forming a protective layer is not a guide, the protective layer and the substrate forming two opposite faces of the transmitter perpendicular to the side faces of the laser activating ions being contained in the substrate and / or in one of the layers. In the case of an internal cavity, a semi - reflecting mirrors (9, 10) are arranged on the lateral faces of the transmitter.
