摘要: Parity-time ($\mathcal{PT}$) symmetry is one of the most important accomplishments in optics over past decade. Here concept $\mathcal{PT}$ mode-locking a laser introduced, which active phase locking cavity axial modes realized by asymmetric mode coupling complex time crystal. shows transition from single to double pulse emission as breaking point crossed. The can show turbulent behavior, depending on dimensionless modulation parameter that plays same role Reynolds number hydrodynamic flows.
