摘要： A ceramic body is disposed in a path of light emitted by a light source. The light source may include a semiconductor structure comprising a light emitting region disposed between an n-type region and a p-type region. The ceramic body includes a plurality of first grains configured to absorb light emitted by the light source and emit light of a different wavelength, and a plurality of second grains. For example, the first grains may be grains of luminescent material and the second grains may be grains of a luminescent material host matrix without activating dopant.

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.
