摘要： The present invention relates to a solid-state laser comprising a gain medium (6) of a solid-state host material which is co-doped with Ce3+-ions and ions of a further rare-earth material. The host material is selected such that a lower edge of the 5d band of the Ce3+-ions is energetically higher than an upper lasing state of the ions of the further rare-earth material. This laser can be optically pumped by GaN laser diodes (4) in the wavelength region between 400 and 450 nm and emits laser radiation in the visible wavelength range. With this laser, in particular, a GaN diode laser pumped solid-state laser emitting in the green wavelength region can be realized.

摘要： The present invention relates to a solid-state laser system constituted bya solid-state laser whichis optically pumped by a vertical extended cavity surface emitting laser (VECSEL). The solid-state laser comprises a solid-state laser medium (11) arranged in a laser cavity which consists oftwo resonator cavitymirrors (10, 12), a first of saidcavity mirrors (12) being designed as an outcoupling mirror of saidsolid-state 5 laser and a second of saidcavity mirrors (10) being formed to allow optical pumping of saidsolid-state laser medium (11) through saidsecond cavity mirror (10). In the proposed solid-state laser system, the extended cavity mirror (7) of the VECSEL is constituted byone of the resonator cavity mirrors (10, 12) of the solid-state-laser. The proposed laser system provides an improved conversion efficiency and a highly 10 integrated design.
