Abstract
Abstract A method for efficiently producing a multicolored laser beam. The second harmonic of a 1.06 micron wavelength laser beam is produced from a YAG laser. The second harmonic has a wavelength equal to 0.53 micron. The second and third harmonics of a 1.32 micron wavelength laser beam are simultaneously produced from a second YAG laser. The second harmoic has a wavelength equal to 0.66 micron and the third harmonic has a wavelength equal to 0.44 micron. The produced harmonics from the previous steps are combined to form a multicolored laser beam.
