<p>A superbroadband or multiwavelength laser transmitter source for wavelength-division multiplexing, two-wavelength interferometry, differential lidar and optical storage applications. The superbroadband laser (100) simultaneously emits at multiple wavelengths. The system maintains simultaneous lasing operation in an optical active gain medium at different wavelengths by the use of dispersive cavity. The system creates its own microcavities each lasing at a different wavelength within the fluorescence band of the gain medium. Mode competition in the cavity is absent and spectral range of simultaneous multi-frequency generation is considerably enhanced practically to the spectral width of the active media luminescence spectrum. As a result, the radiation of each mode with its own wavelength is amplified in the active media independently from the simultaneous amplification of the rest of the wavelengths.</p> |
