Abstract
A resonating optical amplifier includes a laser pump cavity defined by a first mirror and a second mirror with a laser pump gain medium configured within a first portion of the laser pump cavity and a Raman amplifier within a second portion of the laser pump cavity. A circulating pump-laser light is introduced to the laser pump gain medium forming a pump signal that is configured to bi-directionally propagate along a beam path within the laser pump cavity. The Raman amplifier is positioned in line with the beam path of the pump signal and operable to impart gain on a seed pulse. The seed pulse and the pump signal are co-aligned and linearly polarized.
