Abstract
Narrow spectral modes comprising the generation spectrum of a random fiber laser near the threshold are of a great interest in both fundamental aspect and possible applications. The narrow bandwidth, stochastic generation nature, and relatively short lifetime lodge significant issues on the experimental equipment and utilized investigation methods. Possible attitudes for experimental registration and characterization of these modes are discussed in the present paper.
