We report a framing imaging based on noncollinear optical parametric amplification(NCOPA),named FINCOPA, which applies NCOPA for the first time to single-shot ultrafast optical imaging. In an experime
A method of locking the relative phase to provide stable constructive or destructive interference between the phase-modulated sidebands from a pair of phase modulators is demonstrated. It is discussed theoretically for optimal fringe visibility related to
We theoretically investigate multiple electron rescatterings in high-order harmonic generation with a wide range of driving laser wavelengths. In order to obtain a clear and intuitive insight, the time-frequency analysis of the dipole acceleration calcula
