A single-shot experimental method is proposed to study non-repetitive evolutions of high order solitons. In our experiments, high order solitons are prepared in the building up process of a soliton fiber laser, and the order of high order soliton is controlled via changing the parameters of the laser. The evolution of high order soliton is recorded by the single-shot spectral measurements-time stretch dispersive Fourier transform. A 4th order soliton evolution under perturbations of gain saturation and saturable loss is studied, showing how a leading pulse wins the competition against the tailing one. Our work provides a controllable technique to study the high order solitons evolutions, which can be applied in the research of ultrafast laser amplifications and supercontinuum generations.
