1. An extremely high frequency electrical generator comprising;

  • means for generating a collimated coherent light beam along a first path;

    beam splitting means oriented along said first path for splitting said light beam into two components, one of said components being directed along a second path, and the other of said components being directed along a third path, said second and third paths being non-coincident;

    a first frequency selective element means oriented along said second path for receiving said one component and reflecting back, along said second path, toward said beam splitting means, light at the wavelength λ

    1 ;

    a second frequency selective element means oriented along said third path for receiving said other component and reflecting back, along said third path, toward said beam splitting means, light at the wavelength λ

    2 ;

    whereby said beam splitting means combines said light at said wavelengths λ

    1 and λ

    2 along a fourth path; and

    a photodetecting means oriented along said fourth path for receiving light at said wavelengths λ

    1 and λ

    2 and for providing electrical signals at the wavelength, |λ

    1

    2 |.
