Pulsating solitons are intriguing objects in laser physics and nonlinear science. Recently, emerging works on the pulsating multi-solitons have raised interest interactions synchronizations within multiple breathers. However, with their separation of order nanoseconds, evolution underlying dynamics remain uncharted. In this work, we bring initial insights into dual-soliton (PDS) a three orders magnitude pulse duration. Chaotic, synchronous, asynchronous pulsations revealed to be controlled by pump power. Specifically, two can pulsate synchronously form frozen limit cycle. The PDS at high power brings rotating cycle phase space. Unveiling evolutionary PDS, work has potential all-optical storage, signal encoding, time division multiplexing communications.
