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.

摘要： The present invention relates to an all-solid state UV laser system comprising at least one semiconductor laser (10) in a VECSEL configuration. The gain structure (3) in this semiconductor laser (10) emits fundamental radiation in a wavelength range which can be frequency doubled to wavelengths in the UV region. The frequency doubling is achieved with a nonlinear optical crystal (6) for second harmonic generation arranged inside the extended cavity of the semiconductor laser (10). By electrically pumping of the semiconductor laser wavelengths below 200 nm can be efficiently generated with already known semiconductor materials like GaN. The proposed UV laser system is compact and can be fabricated and operated at low costs compared to UV excimer lasers.
