摘要： A laser projection system includes at least one laser light source, a projection screen and a spatial light modulator for projecting a laser beam of the laser light source to form an image on the projection screen. The projection screen includes a luminescent layer which upon excitation by the laser beam emits blue light. The luminescent layer contains MSi6−aAlaN8−aOx+a:Eu2+ (with M=Sr, Ba,; 0≦x≦1; 0≦a≦1) as a luminescent material. With this material laser light of a laser diode emitting in the wavelength region of 405 nm can be converted to blue light of 450 nm with high efficiency. The proposed projection system, therefore, is suitable for RGB projection using laser diodes as laser light sources.

摘要： The invention relates to a laser (1) for emitting laser light in the visible spectral range. A rare earth doped anisotropic crystal (2) comprising a 5d-4f transition is arranged within a laser resonator (7, 8), and a pumping light source (3) pumps the crystal (2) for generating laser light in the visible spectral range by using the 5d-4f transition. The 5d-4f transition of the rare earth doped anisotropic crystal comprises an absorption band extending over several nm. Thus, pump light having a wavelength within a relatively broad wavelength range can be used. This reduces the requirements with respect to the wavelength accuracy of the pumping light source and, thus, more pumping light sources of an amount of produced pumping light sources can be used for assembling the laser, thereby reducing the amount of rejects.
