Quasi-monoenergetic Electron Beams from Laser-plasma Acceleration by Ionization-induced Injection in Low- density Pure Nitrogen
Mengze Tao, Nasr A. M. Hafz, Song Li +5
We report a laser wakefield acceleration of electron beams up to 130 MeV from laser-driven 4-mm long nitrogen gas jet. By using a moderate laser intensity (3.5*10^18 W.cm^(-2)) and…
Enhanced electron yield from a laser-plasma accelerator using high-Z gas jet targets
Mohammad Mirzaie, Nasr A. M. Hafz, Song Li +5
An investigation of the multi-hundred MeV electron beam yield (charge) form helium, nitrogen, neon and argon gas jet plasmas in a laser-plasma wakefield acceleration experiment was…
Interferometric characterization of pulse front tilt of spatiotemporally focused femtosecond laser pulses for three-dimensional micromachining application
Zhaohui Wang, Fei He, Jielei Ni +6
We report on an experimental measurement of the pulse front tilt (PFT) of spatiotemporally focused femtosecond laser pulses in the focal plane in both air and bulk transparent mate…
Fabrication of an integrated high-quality-factor (high-Q) optofluidic sensor by femtosecond laser micromachining
Jiangxin Song, Jintian Lin, Jialei Tang +6
We report on fabrication of a microtoroid resonator of a high-quality factor (i. e., Q-factor of ~3.24x10^6 measured under the critical coupling condition) integrated in a microflu…
Fabrication of three-dimensional microdisk resonators in calcium fluoride by femtosecond laser micromachining
Jintian Lin, Yingxin Xu, Jialei Tang +5
We report on fabrication of on-chip calcium fluoride (CaF2) microdisk resonators using water-assisted femtosecond laser micromachining. Focused ion beam (FIB) milling is used to cr…
