A cascaded Raman laser () has a pump radiation source () emitting at a pump wavelength &#x3bb;, an input section () and an output section () made of an optical medium. Each section () comprises wavelength selectors (and) for wavelengths &#x3bb;, &#x3bb;, . . . , &#x3bb;, where n&#x2267;3, &#x3bb;&#x3c;&#x3bb;&#x3c;&#x3bb;&#x3c; . . . &#x3c;&#x3bb;&#x3c;&#x3bb;and &#x3bb;, &#x3bb;, . . . , &#x3bb;being k&#x2267;1 emitting wavelengths of the laser (). The laser further comprises an intracavity section () that is made of a non-linear optical medium, has a zero-dispersion wavelength &#x3bb;and is disposed between the input () and the output () section. The wavelengths &#x3bb;, &#x3bb;, . . . , &#x3bb;of the wavelength selectors (and) and the zero-dispersion wavelength &#x3bb;of the intracavity section () are chosen such that energy is transferred between different wavelengths by multi-wave mixing.
