Abstract
A laser-phosphor device is disclosed wherein laser radiation from a laser array is transmitted via a collimating primary optical unit and via an imaging optical system onto a phosphor layer. The laser arrangement has a plurality of lasers, for example laser diodes. Via the imaging optical system, a reduced imaging of the laser radiation distribution of the primary optical unit is produced on the phosphor layer.
Claims12
A laser-phosphor device, in which the laser radiation of a laser array can be transmitted via primary optics which collimate the laser radiation and via an optical system onto a phosphor layer, the laser array comprising a multiplicity of lasers, wherein the optical system is configured as an imaging optical system with which a reduced image of a part, passed through by the laser beam, of a plane which extends perpendicularly to the optical axis of the system and lies at least in the vicinity of the primary optics can be generated on the phosphor layer.
