Abstract
We report the realization of a photonic crystal random fiber laser (RFL) doped with different gain media. We studied the small-signal gain of devices by the variable stripe length technique and the effect of polyvinyl pyrrolidone (PVP) polymer on the random lasing. PVP significantly improved the features of the RFL because of the increase in scattering mean free path. We also systematically measured random lasing parameters, including threshold, linewidth, and polarized characteristics. Finally, time-dependent theory for random lasers was used to explain the evolution of the lasing spectrum.
期刊介绍:
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
