    Area of Science:

    • Nanophotonics
    • Quantum Optics
    • Materials Science

    Background:

    • Random lasing relies on coherent feedback from scattering.
    • Plasmonic nanoparticles can enhance light-matter interactions.

    Purpose of the Study:

    • To demonstrate random lasing using plasmonic gold nanostars.
    • To investigate the effect of gold nanostars on lasing properties.
    • To explore applications in nanoscale coherent light sources.

    Main Methods:

    • Embedding gold nanostars in a rhodamine 6G dye gain medium.
    • Analyzing lasing spectra and threshold characteristics.
    • Coating optical fiber tips with gold nanostars for signal collection.

    Main Results:

    • Observed narrow random lasing peaks (FWHM ~0.8 nm) with gold nanostars, compared to broader amplified spontaneous emission (6 nm) from free dye.
    • Achieved a two-fold lower lasing threshold with gold nanostars.
    • Demonstrated guided random lasing signal collection via optical fiber.

    Conclusions:

    • Plasmonic gold nanostars act as efficient scattering centers for random lasing.
    • This approach enables low-threshold, nanoscale coherent light generation.
    • Potential applications include remote sensing, information processing, and on-chip light sources.
