Generally, the principle of linear superposition is not applicable in nonlinear systems. The results of our researches prove that for some certain types of decomposed solutions of (2+1)-dimensional Caudrey–Dodd–Gibbon–Kotera–Sawada(CDGKS) equ

In this work, we consider the (3+1)-dimensional Burgers equation with variable coefficients, which is frequently used to define the motion of solitary waves. Abundant lump waves are constructed by taking the ansatz as a rational function. Furthermore

The residual symmetry of the KdV6 equation is obtained by the Painlevé truncate expansion. Since the residual symmetry is non-local, five field quantities are introduced to localize it into the local one. Besides, the interaction solutions between s

We demonstrate multi-stage ytterbium-doped fiber amplifiers (YDFAs) seeded with a superluminescent light emitting diode (SLED). Laser pulses with four pulse durations, such as 350-ps, 6-ns, 55-ns, and 183-ns (full width half maximum), have been studi

Pulsed pump is an effective method to suppress the amplified spontaneous emission (ASE) between pulses of high power pulsed fiber lasers. For the pulsed pump, the most important factors need to be determined during amplifier design are the pump power

High efficiency, good robustness, and low amplified spontaneous emission are among the key factors of the high power ytterbium-doped pulsed fiber laser. In this letter, we propose an optimized pulsed pumping design for the nanosecond ytterbium-doped
