Radiation build-up and dissipation in Raman random fiber laser

Raman random fiber lasers (RRFL) have attractive features, such as their simple structure, excellent wavelength-tunability and high optical-optical conversion efficiency. They show great potential for long-distance fiber sensing, speckle-free imaging, high-energy physics, and other applications. The unique feedback in the RRFL comes from distributed fiber Rayleigh scattering with intrinsic randomness.
