INTERLOCKED RING INTRACAVITY RAMAN LASER AND METHOD OF GENERATING RAMAN SHIFTED LASER OUTPUT

摘要

Abstract of DisclosureDevice for providing a train of light pulses atRaman shifted frequency comprises a first ring laser(for fundamental frequency) and a second ring laser (forRaman shifted frequency). Both ring laser intersect ina Raman laser medium which is common to the cavity ofboth ring lasers. The Raman cavity has output meanspartially transmissive at Raman frequency. Length offirst and second ring laser cavities differs by .DELTA.L.Injection of a fundamental pump pulse and a small Ramanseed pulse into their respective cavities results inoutput of a train of Stokes pulses.
