Abstract
A desired N-order Stokes output and corresponding zeroth-order Stokes pump wavelengths are seeded into a Raman amplifier comprised of one or more Raman resonators in series sequentially tuned to the 1, 2, . . . N−1Stokes orders. The pump wavelength is amplified and sequentially converted to the 1, 2, . . . N−1order Stokes wavelengths as it propagates through the apparatus. The desired N-order Stokes output wavelength is then amplified by the N−1Stokes order as it propagates through the final resonator tuned to the N−1Stokes order. Each Raman resonator includes a Raman photosensitive Raman fiber located between a pair of Bragg gratings. The linewidths of the various Stokes orders can be controlled through adjusting the resonant bandwidths of the Raman resonators by offsetting, through heating, the reflectivity bandwidths of each pair of Bragg gratings respectively located in the Raman resonators.
