Abstract
Apparatus and method for synthesizing laser light characterized by a plurality of discrete wavelengths, without competition among different wavelengths. A preferred embodiment of the invention includes a laser resonator having an optical cavity bounded by a first, reflective end plate; a gas-filled chamber having a pair of Brewster windows, within the optical cavity; and a Brewster angle Pockels cell between one Brewster window and the partially reflective end plate. The laser resonator generates red, blue and green laser light simultaneously and the Pockels cell transmits red, blue and green light successively, at a rate of at least 30 cycles per second, so that the resulting laser beam appears white in color.
