Supercontinuum light sources with both highly flatness and highly coherence have unique application advantages in biological imaging, optical frequency comb, and optical coherence tomography. We demonstrate the generation of a highly coherent flat supercontinuum spectrum. In order to achieve broadband flat spectrum generation, we used a highly nonlinear fiber with a nominal dispersion of zero at 1550 nm and a dispersion slope of less than 0.025 ps/(nm2·km). Meanwhile a sub 100 fs fiber laser was used as the pump source in the experiment to achieve good coherence. When the pump power was 134 mW, the supercontinuum emission was characterized between 1197 nm and 2242 nm, showing the flat spectrum with 10 dB uniformity was obtained at the wavelength region of 1603–2242 nm and wide spectrum with a conversion efficiency over 85%. The coherence of the supercontinuum spectrum was 1 in the range of 1200–2242 nm by theoretically studying the coherence characteristics of the supercontinuum spectrum. In addition, the effect of pump laser duration on spectral flatness was demonstrated through experiments. Our experiment provides a feasible method for the generation of near-infrared flat highly coherence supercontinuum spectrum with all optical fibers structure.

“…The output power is raised by means of a second amplifier (EDFA L26) with 26 dBm output saturation power (Manlight, model HWT-EDFA-GM-SC-BO-L26). The TDF sample amplifies a pulsed SC source, which is formed by an ultrafast erbium-doped fiber laser (EDFL) and a silica HNLF sample (YOFC, model NL1016-B) [17]. The EDFL is pulsed by passive mode-locking based on the NPR.…”

An efficient and straightforward method to obtain all-fiber pulsed sources at 2 μm is presented and experimentally demonstrated. It is based on the soliton self-frequency shift effect in a highly nonlinear fiber. The output power of a supercontinuum source is previously increased by an optimized homemade thulium-doped fiber amplifier. By coupling the amplified output power in a highly nonlinear fiber, the spectrum is shifted toward 130 nm and the spectral peak is located at 2014 nm. The power conversion factor reaches values as high as 0.93, without employing additional amplifiers. The mean spectral power of the 2 μm source reaches -4.6 dBm/nm (0.35 mW/nm), its output power is 38 mW and the peak power of each pulse is higher than 27 kW.
