“…4 illustrates the spectral evolution of SC with different pump power. When the pump power is 1 W, amplified spontaneous emission (ASE) with parasitic laser spikes is demonstrated in the red curve [25]. With the pump power further increasing, a few spectral spikes with narrow bandwidth and different locations are superimposed randomly on the output spectra (magenta curve in Fig.…”

An all-fiber supercontinuum (SC) laser source with 50.7 W average output power and spectrum ranging from 500 nm to 2400 nm is demonstrated. With the generation of high peak power nanosecond pulses and photonic crystal fiber (PCF) in the self-Q-switched fiber laser, the output SC shows good spectral width and flatness which has a 20 dB bandwidth of 1900 nm except the 1064 nm peak. The effect of the PCF length on the spectral characteristics and output power of SC were carefully studied. To the best of our knowledge, this is the highest power of SC generated in a single-stage fiber laser with such a broadband spectrum. This ultra-compact SC generation method has the merits of simple structure, low cost and good robustness, which provide an easily available SC generation method for various practical applications.

“…They attract much attention for their useful characters of short coherence length, high thermal stability, and broad spectra [1][2][3]. In particular, Yb-doped superfluorescent fiber sources exhibit advantages in terms of high output power and, thus, have been applied in a variety of fields [4,5].…”

A high-power all-fiber broadband superfluorescent source is fabricated by using a distributed side-coupled cladding-pumped Yb-doped fiber. It is found experimentally that besides the optical feedback, the active fiber parameters have a significant effect on the power scaling. By optimizing the fiber length, a record amplified spontaneous emission output of 186.3 W is achieved, and the slope efficiency with respect to launched pump power is 78%. The bandwidths are larger than 20 nm. Furthermore, the power scalability of the superfluorescent source is analyzed numerically. The parasitic laser oscillation can be suppressed further with a large core to cladding ratio.

“…In contrast to conventional fiber lasers, SFSs also have characteristics such as no parasitic oscillation and a self-pulsing mode [4]. The combination of these characteristics makes high-power SFSs a potential pump source for precise materials processing, the investigation of nonlinear phenomenon, Raman lasers, and super-continuum generation [5][6][7].…”

In this paper we demonstrate an all-fiberized superfluorescent fiber source that has a maximal output power of 2.53 kW and is based on a single-stage power amplification configuration. The seed source is a broadband-amplified spontaneous emission source with a full output power of 27.6 W. A single-stage dual-clad fiber amplifier is used, in which the maximal optical-to-optical conversion efficiency is 81.47%. A beam quality of M2 = 1.53 is measured at an output power of 1 kW. At maximum output power, the central wavelength and full width at half maximum linewidth of the amplified light are 1082.08 nm and 6.32 nm, respectively. No conspicuous spike was observed at the stimulated Raman scattering wavelength. The corresponding power fluctuation is 2.97%, which indicates the good power stability of the broadband high-power superfluorescent fiber source (SFS) system. This kilowatt-class high-power all-fiberized SFS system which has high conversion efficiency and good power stability and is based on a compact single-stage power-scaling scheme, is an alternative and competitive solution for industrial precision processes and special stabilized pumping. To the best of our knowledge, this is the highest power SFS ever reported, and the first demonstration of a high-power SFS with a kW-level output power in a compact single-stage power-scaling scheme.
