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…
All-angle collimation of incident light in -near-zero metamaterials
Vladimir Yu. Fedorov, Takashi Nakajima
We use the theory of inhomogeneous waves to study the transmission of light in -near-zero metamaterials. We find the effect of all-angle collimation of incident light, which mea…
Negative refraction of inhomogeneous waves in lossy isotropic media
Vladimir Yu. Fedorov, Takashi Nakajima
We theoretically study negative refraction of inhomogeneous waves at the interface of lossy isotropic media. We obtain explicit (up to the sign) expressions for the parameters of a…
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…
