Abstract

We present a new design of a random Raman fiber laser that allows to generate narrow spectral peaks with a high rate, based on a multimode gradient fiber as a media composing the cavity. The proposed scheme is simple for implementation and analysis. We carry out spectral measurements using optical heterodyning technique by projecting multimode radiation onto the fundamental mode of a standard single-mode fiber. The measurements confirmed the presence of localized ultra-narrow short-lived modes. Compared with single-mode fiber based random Raman lasers, the number of localized modes observed per unit time in a given spectral range is significantly higher.
