According to an embodiment of the disclosure, a Raman generator includes a Raman medium (410, 510) and one or more optical elements (415a, 415b, 415c, 415d, 515a, 515b). The Raman medium is configured to receive a pump pulse at a first wavelength and shift at least a portion of the pump pulse energy or power into a Stokes-shifted pulse at a second wavelength. The one or more optical elements (415a, 415b, 415c, 415d, 515a, 515b) are configured to synchronize one or more subsequent passages of the Stokes-shifted pulse through the Raman medium with one or more subsequent pump pulses at the first wavelength. The synchronized passage of the Stokes-shifted pulse and one or more subsequent pump pulses through the Raman medium increases a power of the Stoke-shifted pulse. |
