Patent Abstract

The method involves producing a longitudinal mode by light reflection devices (1a,1b) in the resonator, whose wavelength depends on the resonator length. The transverse modes are generated by the curvature of light reflection devices. The wavelength of photons in the resonator is interacted with the mechanical vibrations of the reflection units (2) for generating the reflections. The light reflection devices in the transverse direction are displaced to the direction of the long wavelength of the next input spectral wavelength distribution in the longitudinal mode. An independent claim is included for a light source.
