    Researchers developed a novel fiber laser emitting radially directed light from its surface, unlike traditional fiber lasers. This innovation opens doors for advanced medical imaging and display technologies.

    Area of Science:

    • Optics and Photonics
    • Materials Science

    Background:

    • Conventional fiber lasers emit light axially along the fiber.
    • Existing technologies lack radially directed emission capabilities.

    Purpose of the Study:

    • To demonstrate a novel fiber laser with radially directed emission.
    • To explore the underlying optical principles and potential applications.

    Main Methods:

    • Utilized a cylindrical photonic bandgap fiber resonator.
    • Incorporated anisotropic organic dye gain and a linearly polarized axial pump.
    • Achieved controlled azimuthal anisotropy in the optical wavefront.

    Main Results:

    • Demonstrated radially directed laser emission from the fiber's circumferential surface.
