1. Direct measurements of localized spectral modes in random distributed feedback fiber laser

Subjects
Fiber laser, Random laser, Raman laser, Rayleigh backscattering, Physics, QC1-999
Abstract

We present observation of ultra-narrow spectral modes in the generation of the random fiber laser by using a technique of optical heterodyning in real-time. We found that such modes have a spectral width below 3 MHz. The modes are spatially extended over the whole cavity and remain for tens of roundtrip times.
