Fast predicting the complex nonlinear dynamics of mode-locked fiber laser by a recurrent neural network with prior information feeding

Guoqing Pu, Runmin Liu, Hang Yang +4

As an imperative method of investigating the internal mechanism of femtosecond lasers, traditional femtosecond laser modeling relies on the split-step Fourier method (SSFM) to iter…

Collision-induced Hopf-type bifurcation reversible transitions in a dual-wavelength femtosecond fiber laser

Runmin Liu, Defeng Zou, Shuang Niu +2

Collision refers to a striking nonlinear interaction in dissipative systems, revealing the particle-like properties of solitons. In dual-wavelength mode-locked fiber lasers, collis…

Chaotic internal dynamics of dissipative optical soliton molecules

Youjian Song, Defeng Zou, Omri Gat +2

When a laser cavity supports the propagation of several ultrashort pulses, these pulses interact and can form compact bound states called soliton molecules. Soliton molecules are f…

Synchronization of the internal dynamics of optical soliton molecules

Defeng Zou, Youjian Song, Omri Gat +2

Optical soliton molecules in ultrafast lasers present striking analogies with their matter molecule counterparts, such as internal vibrations. However, the vibrations of soliton mo…

Narrow-linewidth optical frequency comb reference to a fiber delay line

Haochen Tian, Fei Meng, Baike Lin +4

In this letter, we derive a fully-stabilized narrow-linewidth optical frequency comb (OFC) reference to a kilometer-long fiber delay line for the first time, to the best of our kno…

Chromatic annuli formation and sample oxidation on copper thin films by femtosecond laser

Shutong He, Salvatore Amoruso, Dongqing Pang +2

We report an experimental investigation on the irradiation of copper thin films with high repetition rate femtosecond laser pulses (1040 nm, 50 MHz), in ambient air and liquid wate…

Photostimulation activates restorable fragmentation of single mitochondrion by initiating oxide flashes

Yintao Wang, Hao He, Shaoyang Wang +4

Mitochondrial research is important to ageing, apoptosis, and mitochondrial diseases. In previous works, mitochondria are usually stimulated indirectly by proapoptotic drugs to stu…
