Abstract
The present invention provides for multiple wavelength laser sources. The laser source has a pumping laser generating output at a wavelength, typically below 1500 nm, and a plurality of DBR fiber lasers or DFB fiber lasers, each having an output which is centered at a selected wavelength in the 1550 nm range. The fiber lasers are connected to the pumping laser such that the output light from said first pumping laser provides lasing energy for each of said fiber lasers. The fiber lasers may be connected serially or in series to each other. An optical fiber amplifier may be connected to the output of the serially-connected fiber lasers, or to the output of each one of the parallel-connected fiber lasers, to amplify the output from the fiber lasers so that the pumping laser provides energy for both the fiber lasers and the optical fiber amplifier.
