Cascaded long pulse and continuous wave Raman laser

摘要

A Raman laser apparatus having an n-th order Stokes shifted output, the apparatus comprising: a laser pump input; A lasing cavity having a feedback member at each end; A diamond Raman active gain medium in the cavity, the Raman active gain medium exhibiting primary and higher Stokes emission when pumped by the laser pump input; The feedback member feeds back the gain portion of the pump input, the primary Stokes output from the gain medium and the upper Stokes output, and the transmitter of the n-th Stokes output is the output of the device.
