Abstract
In accordance with the present invention a multifrequency Raman pump laser cavity is disclosed comprising of an angularly dispersive element optically coupled to a shared waveguide terminated in a partially reflecting facet; a plurality of laser diode sources for radiating at frequencies for Raman amplification each for providing laser light at a different frequency and spatially oriented in relation to the angular dispersive element such that light emitted from each source is reflected from the angularly dispersive element toward a same output port; at least two partially reflecting coating for forming a laser cavity therebetween wherein the grating is within the laser cavity or defines a boundary thereto.
