High-energy tunable ultraviolet pulses generated by optical leaky wave in filamentation
Litong Xu, Tingting Xi
Ultraviolet pulses could open up new opportunities for the study of strong-field physics and ultrafast science. However, the existing methods for generating ultra-violet pulses fac…
Generation of high quality sub-two-cycle pulses by self-cleaning of spatiotemporal solitons in air-plasma channels
Litong Xu, Tingting Xi
The temporal sidelobes of few-cycle pulses seriously restrict their applications in ultrafast science. We propose a unique mechanism that enables the generation of sub-two-cycle pu…
Few-cycle vortex beam generated from self-compression of mid-infrared femtosecond vortex beam in thin plates
Litong Xu, Dongwei Li, Junwei Chang +2
We demonstrate theoretically that few-cycle vortex beam with subterawatt peak power can be generated by self-compression of mid-infrared femtosecond vortex beam using the thin-plat…
Powerful supercontinuum vortices generated by femtosecond vortex beams with thin plates
Litong Xu, Dongwei Li, Junwei Chang +3
We demonstrate numerically and experimentally the generation of powerful supercontinuum vortices from femtosecond vortex beams by using multiple thin fused silica plates. The super…
