Laser device used in laser TV, has refractive dispersion merging component that merges single output beams depending on emission wavelength to produce overall output beam

摘要

The laser device (1) has several laser diodes (2-4) whose output beams (5-7) are superimposed to form an overall output beam (8). The laser diode has a temperature control unit (10) for controlling an actual temperature of the respective laser diode to a desired temperature. The individual output beams of the laser diodes have different emission wavelengths. A refractive dispersion merging component (11) merges the single output beams depending on the emission wavelength to produce overall output beam. An independent claim is included for a method for superposition of single output beams of laser diodes to overall output beam.
