On-chip tuning of the resonant wavelength in a high-Q microresonator integrated with a microheater
Jialei Tang, Jintian Lin, Jiangxin Song +5
We report on fabrication of a microtoroid resonator of high-quality (high-Q) factor integrated with an on-chip microheater. Both the microresonator and microheater are fabricated u…
Plasma waves excited at interface by femtosecond laser irradiation enabling formation of volume nanograting in glass
Yang Liao, Jielei Ni, Lingling Qiao +4
Irradiation of intense ultrafast laser pulses in glasses can lead to formation of nanogratings whose periods are significantly smaller than the incident irradiation wavelength. The…
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…
Second harmonic generation in a high-Q lithium niobate microresonator fabricated by femtosecond laser micromachining
Jintian Lin, Yingxin Xu, Zhiwei Fang +5
We report on fabrication of high Q lithium niobate (LN) whispering-gallery-mode (WGM) microresonators suspended on silica pedestals by femtosecond laser microfabrication. The micro…
