OPTIMAL COLORS FOR A LASER PICO-BEAMER

摘要

A laser beam projector employs a light engine including a semiconductor laser platform (20) emitting a plurality of infrared laser beams and a frequency converter (30) emitting a plurality of primary color laser beams as a frequency conversion of the plurality of infrared laser beams, wherein each primary color laser beam has a primary color wavelength corresponding to a maximum sensitivity of a human eye. The laser beam projector further employs a laser beam mixer (40) operable emitting a projection laser beam as a mixture of the plurality of primary color laser beams.
