    We explore for the first time the real-time spectra of dissipative solitons (DS) and noise-like pulse (NLP) inter-switching by adjusting the pump power, as well as dual-pulse collision dynamic for three modes: dual-NLP, NLP-DS, and dual-DS in a single-/dual-wavelength mode-locked fiber laser. Different types of dual-pulse differ in collision duration. During spectral reconstruction, dual-pulse exchange energy twice due to their respective accumulation dynamics. Additionally, collision-induced soliton explosions have chaotic properties, leading to each collision being random. The experimental results advance the study of the dynamics of different pulse types and also contribute to conducting in-depth investigations on dual-comb sources. Keywords: ytterbium-doped fiber laser; single-/dual-wavelength; different pulse types; real-time spectra.
