“…Supercontinuum is generated during the transmission of optical pulses through highly nonlinear optical fibers, and the spectrum is greatly broadened due to nonlinear effects and dispersion effects such as self-phase modulation. The traditional supercontinuum generation method of photonic crystal fiber pumped by fiber laser has the advantages of wide spectral range and high spectral flatness [1] . The supercontinuum generated by random fiber laser has the advantages of simple structure, low cost and good robustness [17] , and the coherence of supercontinuum is lower than that of traditional fiber laser pumped PCF output [18] .…”

The Supercontinuum (SC) has certain advantages in atmospheric transmission by virtue of its wide spectrum, high brightness and good directionality, etc. In this paper, two SC sources, laser-pumped photonic crystal fiber generating supercontinuum and random fiber laser structure outputting supercontinuum, are used to carry out an experimental study of atmospheric transmission at a distance of about 1 km. By analyzing the changes of power, time domain, spectrum and spot distribution pre- and post-transmission, the effect of atmospheric turbulence on the supercontinuum transmission is studied from the experimental point of view, which lays a solid foundation for future space transmission applications of SC.

A numerical investigation was conducted to obtain a supercontinuum spanning about two octaves using a large mode area photonic crystal fiber (PCF) pumped at 1.3 μm. In our study, a 1.3 μm femtosecond laser and a silica-based large mode area PCF were selected as the pump source and nonlinear medium, respectively. The nonlinear Schrodinger equation was solved with split-step Fourier method to simulate the evolution of pulse and the broadening of spectrum. The effect of several parameters including the length of PCF, the pulse width, and the average pump power on characteristics of the output spectrum was studied. The simulation results revealed that the supercontinuum extended from near 600 nm to over 2450 nm at 20 dB with length of 30 cm, pulse width of 100 fs and average power of 12 W, respectively. This work proved this large mode area PCF a potentially excellent medium for supercontinuum source and provided some theoretical guidance for future experiments.

“…In recent years, researchers have found that partially coherent lasers can reduce the effect of turbulence on transmission 4,5 , while the unique characteristics of supercontinuum with good spatial coherence and low temporal coherence are well suited for atmospheric transmission studies 6 . The supercontinuum laser also has the characteristics of wide spectrum, high brightness, good directionality [7][8][9] , which possess prevailing advantages in atmospheric transmission research [10][11][12] . The nonlinear medium is affected by nonlinear effects such as self-phase modulation and dispersion effects 13,14 that cause the spectrum to be greatly broadened so that the supercontinuum can be generated.…”

Supercontinuum laser has been paid more and more attention in recent years because of its wide spectral range and good directivity. Research on the transmission of supercontinuum laser in atmosphere is beneficial to its practical application. Supercontinuum generated by pumping a piece of photonic crystal fiber with output power of ~4.9W and generation directly in a random fiber laser with output power of ~2W were used in a 850 m transmission field tests respectively. The test was based on a Newtonian telescope to collimate and expand the laser, apply a real-time measurement of the ontarget power with an optical power meter at the receiving place. Experimental results show that the supercontinuum generated by random fiber laser can reduce the atmospheric impact more effectively than the other one.
