Special Issue Information

Dear Colleagues,

Fiber lasers, as third-generation lasers, are widely used in material processing, optical communication, fiber sensing, and other fields in recent years because of their excellent beam quality and high optical conversion efficiency. In the last decade, numerous theoretical and experimental results have been reported on the generation of mode-locked lasers, continuous high-power tunable fiber lasers, and ultrafast fiber laser communications. However, the practical application of fiber laser technology still faces many challenges, such as pulse compression and amplification technology, frequency stabilization, and noise suppression of mode-locked pulses. This Special Issue, “Advancements in Fiber Lasers and Their Applications”, welcomes fundamental methodological and applied cutting-edge research contributions. Topics include, but are not limited to, the following:

  • High-power fiber lasers;
  • Ultrafast fiber lasers;
  • Tunable fiber lasers;
  • Narrow-linewidth fiber lasers;
  • Mid-infrared fiber lasers;
  • Frequency combs;
  • Fiber laser applications.

We look forward to receiving your contributions.

Abstract
The cavity form of complex microcavity lasers predominantly relies on disordered structures, whether found in nature or artificially prepared. These structures, characterized by disorder, facilitate random lasing through the feedback effect of the cavity boundary and the internal scattering medium via various mechanisms. [...] Read more.
The cavity form of complex microcavity lasers predominantly relies on disordered structures, whether found in nature or artificially prepared. These structures, characterized by disorder, facilitate random lasing through the feedback effect of the cavity boundary and the internal scattering medium via various mechanisms. In this paper, we report on a random fiber laser employing a disordered scattering cladding medium affixed to the inner cladding of a hollow-core fiber. The internal flowing liquid gain establishes a stable liquid-core waveguide environment, enabling long-term directional coupling output for random laser emission. Through theoretical analysis and experimental validation, we demonstrate that controlling the disorder at the cavity boundary allows liquid-core fiber random microcavities to exhibit random lasing output with different mechanisms. This provides a broad platform for in-depth research into the generation and control of complex microcavity lasers, as well as the detection of scattered matter within micro- and nanostructures.
