Source coherence orchestrates nonlinear random wave revivals
Yanlin Bai, Tianyu Cao, Pujuan Ma +4
We demonstrate that the Talbot length of periodic wave packets, long believed to be solely determined by their periodicity, is strongly affected by the source coherence in the nonl…

Regular and irregular revivals of quasi-periodic random waves
Yanlin Bai, Yangjian Cai, Chunhao Liang +1
Paraxial wave packets with discrete spatial, temporal, or spatiotemporal spectra are known to undergo periodic axial revivals on propagation in either free space or linear transpar…

On-Demand Pulse Shaping with Partially Coherent Pulses in Nonlinear Dispersive Media
Qian Chen, Yanlin Bai, Xiaohan Wang +4
In this Letter, we employ the complex screen method to investigate the dynamic evolution of partially coherent pulses with specified properties as they propagate through a nonlinea…
