Optically pumped laser minicavity, its production process and laser using said cavity, wherein the minicavity comprises an electrically insulating, parallelepipedic, solid emitter (1b), having two polished parallel lateral faces (6, 8), a monocrystalline substrate (2) and several monocrystalline layers epitaxied 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) able to guide the light emitted by the emitter and the pumping light and another layer (12) constituting a non-guiding protective layer, the protective layer and the substrate constituting two opposite faces of the emitter perpendicular to the lateral faces, laser activating ions being contained within the substrate and/or in one of the layers. In the case of an internal cavity, semi-reflecting mirrors (9, 10) are placed on the lateral faces of the emitter.
A solid, electrically insulating laser emitting minicavity having a paralellepipedic shape, and a light guiding structure comprising two polished, parallel lateral faces (6, 8), a monocrystalline substrate (2) and a plurality of monocrystalline layers (4, 12, 14) epitaxied one on top of the other on the substrate and having in directions parallel to said faces a hardness equal to that of the substrate, the substrate and the epitaxied layers each being non-cleavable, one of the layers constituting a guide layer (4, 14) able to guide pumping light and light emitted by the minicavity and having a refraction index higher than that of adjacent materials (2, 4, 12) and another layer (12) constituting a non-guiding protective layer, the protective layer and the substrate constituting two opposite faces of the minicavity perpendicular to said lateral faces, laser activating ions being contained within the substrate, one of the epitaxied layers, or both the substrate and one of the epitaxied layers.
