Abstract: The present invention relates to stimulated emission radiation sources and, more precisely, to a dye laser in which the wavelength of the radiation emitted is varied by modifying the voltage applied to a thin film of a cholesteric liquid crystal which replaces one of the mirrors of the resonant optical cavity. This invention can be used as an adjustable wavelength coherent radiation source.

Abstract: The present invention relates to travelling wave frequency converter arrangements based on the harmonic generation. The converter in accordance with the invention comprises a harmonic generation interface obtained by bringing together a metal film and an optical waveguide layer whose thickness is such that the phase velocities of the fundamental and harmonic frequency radiations transmitted are substantially matched with one another. Optical coupling means are associated with the optical waveguide and electrical means may be provided for altering the phase velocity matching.

Abstract: The invention relates to stimulated emission radiation source and more precisely to a dye laser in which the control of the emitted radiation wavelength is effected by varying the quality factor of the resonant cavity by means of a thin film of a nematic liquid crystal arranged between two polarisers, the double-refracting property of the film being controlled by a voltage applied through transparent electrodes.
