Full characterization of few-cycle superradiant pulses generated from a free-electron laser oscillator
Heishun Zen, Ryoichi Hajima, Hideaki Ohgaki
The detailed structure of few-cycle superradiant pulses generated from a free-electron laser (FEL) oscillator was experimentally revealed for the first time. As predicted in numeri…
Present status of source development station at UVSOR-III
Najmeh Sadat Mirian, Jun-ichiro Yamazaki, Kenji Hayashi +6
Construction and development of a source development station are in progress at UVSOR-III, a 750 MeV electron storage ring. It is equipped with an optical klystron type undulator s…
Damage threshold and focusability of mid-infrared free-electron laser pulses gated by a plasma mirror with nanosecond switching pulses
Xiaolong Wang, Takashi Nakajima, Heishun Zen +2
The presence of a pulse train structure of an oscillator-type free-electron laser (FEL) results in the immediate damage of a solid target upon focusing. We demonstrate that the las…
Diagnosis of the Wavelength Stability of a Mid-Infrared Free-Electron Laser
Xiaolong Wang, Yu Qin, Takashi Nakajima +3
Wavelength stability of free-electron lasers (FELs) is one of the important parameters for various applications. In this paper we describe two different methods to diagnose the wav…
Single-shot spectra of temporally selected micropulses from a mid-infrared free-electron laser by upconversion
Xiaolong Wang, Takashi Nakajima, Heishun Zen +2
We demonstrate the measurement of single-shot spectra of temporally selected micropulses from a mid-infrared (MIR) free-electron laser (FEL) by upconversion. We achieve the upconve…
