“…In the experiment, 10 mM PM597 dye served as the gain medium of the random laser, and the peak of gain bandwidth is located near 580 nm. The microfluidic controller ensures that the gain solution is able to be replenished into the fiber random microcavity at any time, thereby mitigating solution volatilization and photobleaching induced by long-term pumping [43].…”

“…This process establishes superior platforms for realizing high-sensitivity sensing applications. Nevertheless, the present solution, predicated on an integrated filling within the optical fiber, conflates scattering and gain media, impeding the exploration and application of laser characteristics sensitive to the axial environment [42,43]. Hence, further in-depth exploration and research are imperative to understand the microcavity disorder distribution and its corresponding random laser mechanism.…”

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.
