ABSTRACT:
A laser is comprised of a lens, a cavity and an excitation source. The lens comprises a paraboloidically/ellipsoidally curved RF photon transparent element comprised of a periodic superlattice of laminated layers of n-doped CdS with lithium reinforcement in the valence band, a periodic superlattice of laminated layers of p-doped CdTe, and an intermediate intrinsic layer of neutral CdS. The lens is separated into three sectors of equal area tuned to emit red, green and blue light in their respective sector. The lens is mounted at one end of the cavity. The excitation is mounted within the cavity and comprises a source of an acoustic microwave beam directed toward the lens. Spiralling red, green and blue beams are produced in the lens and travel at different phase velocities to recombine to produce a single elliptically polarized white beam at one ellipse per cycle.
