“…The first PCF was based on a hexagonal array of air holes and the huge majority of PCFs are based on this approach. However, the unprecedented degrees of freedom provided by this technology include different geometries, such as octagonal structures with isosceles triangular-latticed cladding [91], square-lattice structures [92], core-ring structures [93] and circular rings of air holes [94].…”

High-power fiber lasers have seen tremendous development in the last decade, with output powers exceeding multiple kilowatts from a single fiber. Ytterbium has been at the forefront as the primary rare-earth-doped gain medium owing to its inherent material advantages. However, for this reason, the lasers are largely confined to the narrow emission wavelength region of ytterbium. Power scaling at other wavelength regions has lagged significantly, and a large number of applications rely upon the diversity of emission wavelengths. Currently, Raman fiber lasers are the only known wavelength agile, scalable, high-power fiber laser technology that can span the wavelength spectrum. In this review, we address the technology of Raman fiber lasers, specifically focused on the most recent developments. We will also discuss several applications of Raman fiber lasers in laser pumping, frequency conversion, optical communications and biology.

“…Selective pulse excitation of the mode in the core and the introduction of microbendings along the fibre produces an optical pulse train at the output with different amplitudes and time delays compared to the first (the fastest) pulse train which is carried by the mode in the core. From the delay between the fastest core pulse and the ring pulse, the position of the disturbance along the fibre can be calculated [6,7]. This paper shows experimental investigation of light coupling from the core into the ring caused by a microbending modulator.…”
