摘要：

We present a novel and simple double-pass fiber Raman laser in the visible and near-IR regions, based on the use of a fiberoptic autocollimation technique with Littrow-prism-tuned emission. When the Raman medium is a 40-m-long 68-mu m-core-diam graded-index multimode fiber with powerful (above 100 kW pulse power coupled into the fiber) nanosecond pumping using the second harmonic of a Nd:YAG laser (lambda(p) = 532 nm), we obtain widely tunable generation in both the visible and near-IR. By using the double-pass fiber Raman laser with various lengths of the multimode fiber, continuously tunable generation over a wide spectral range (0.54-1.01 mu m) is obtained.
