研究目的
Investigating the sensitivity of velocities and amplitudes of single-soliton components of high-intensity light pulses with linear frequency chirp and parabolic profile to small harmonic phase perturbations.
研究成果
The study concludes that velocities and amplitudes of single-soliton components of high-intensity light pulses with linear frequency chirp are highly sensitive to small harmonic phase perturbations. This sensitivity must be considered for the characterization and application of such pulses. The effect can also be used to manage the pulse breakup scenario and the separation of stable single-soliton components.
