Device for forming an image with a laser beam

摘要

A device for forming an image with a laser beam is disclosed. The device comprises a laser, means for on-off modulating a laser beam, means for converting a wavelength of the laser beam generated by the laser and means for scanning the laser beam. With means for converting a wavelength of the laser beam, the laser which generates a laser beam, the wavelength of which does not directly meet the requirements, may be adopted to form an image.
