High power tunable Raman fiber laser at 1.2 μm waveband [PDF]

Frontiers of Optoelectronics
Development of a high power fiber laser at special waveband, which is difficult to achieve by conventional rare-earth-doped fibers, is a significant challenge. One of the most common methods for achieving lasing at special wavelength is Raman conversion.
