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…
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…
Gain dynamics of a free-space nitrogen laser pumped by circularly polarized femtosecond laser pulses
Jinping Yao, Hongqiang Xie, Bin Zeng +9
We experimentally demonstrate ultrafast dynamic of generation of a strong 337-nm nitrogen laser by injecting an external seed pulse into a femtosecond laser filament pumped by a ci…
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…
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…
