Abstract

A multiple wavelength laser apparatus is taught to select wavelengths for simultaneous generation of short pulses at multiple wavelengths having application in wavelength-division-multiplexed communications systems, photonic microwave systems, and pump-probe applications. The multiple wavelength laser comprises an optical fiber lasing material, a laser pump source connected to said lasing material for outputting coherent light, a splitter for dividing said coherent light into parallel paths of differing wavelengths, parallel band pass filters for selecting multiple wavelengths, and parallel Faraday mirrors for operating the multiple wavelength laser in a single polarization state.
