Low-threshold efficient N lasing driven by sub-cycle soliton dynamics in a hollow waveguide
Tiandao Chen, Zhiyuan Huang, Jinyu Pan +12
The phenomenon of N lasing, observed in femtosecond-laser filamentation, attract considerable interests in recent several years, with great application potentials in fields…
Enhancement of vacuum-ultraviolet dispersive-wave emission using gas-filled tapered hollow-core fibers
Yinuo Zhao, Donghan Liu, Baoqi Shi +12
The recent breakthroughs in laser-driving 229Th nuclear transition have created an urgent demand for coherent vacuum-ultraviolet (VUV) sources delivering high spectral brightness a…
Flexible delivery of high-power picosecond laser in purely-single optical mode of anti-resonant hollow-core fiber for micromachining
Xinshuo Chang, Qinan Jiang, Zhiyuan Huang +11
We present the flexible delivery of picosecond laser pulses with up to 20 W average power over a 3-m-long sample of anti-resonant hollow-core fiber (AR-HCF) for laser micromachinin…
Tunable ultraviolet dispersive-wave emission driven directly by 40-fs Ti: sapphire laser pulses in hollow capillary fiber
Tiandao Chen, Zhiyuan Huang, Jinyu Pan +8
We demonstrate that by using 1-m-long gas-filled hollow capillary fiber (HCF) with a core diameter of 100 μm, tunable ultraviolet (UV) dispersive-wave (DW) pulses can be generated…
Retiming dynamics of harmonically modelocked laser solitons in a self-driven optomechanical lattice
Xiaocong Wang, Benhai Wang, Wenbin He +6
Harmonic mode-locking, realized actively or passively, is an effective technique for increasing the repetition rate of lasers, with important applications in optical sampling, lase…
Octave-wide broadening of ultraviolet dispersive wave driven by soliton-splitting dynamics
Tiandao Chen, Jinyu Pan, Zhiyuan Huang +9
Coherent dispersive wave emission, as an important phenomenon of soliton dynamics, manifests itself in multiple platforms of nonlinear optics from fibre waveguides to integrated ph…
