ELECTRONIC APPLIANCE, AND METHOD FOR COMBINING TOGETHER LASER LIGHT

摘要

An electronic appliance has a first polarization convertible diffraction device which splits laser light emitted from a light source into a plurality of components of the laser light; a second polarization convertible diffraction device which combines together the plurality of components of the laser light into combined laser light; an optical path length adjuster which adjusts the optical path length difference between the plurality of components of the laser light along the path between the first and second polarization convertible diffraction devices; and an angle-of-incidence adjuster which adjusts, to predetermined angles, the angles of incidence at which the plurality of components of the laser light are respectively incident on the second polarization convertible diffraction device.
