Nonlinear optical processes are governed by the relative-phase relationships among the relevant electromagnetic fields in these processes. In this Letter, we describe the physics o…
Coherent phonon induced optical modulation in semiconductors at terahertz frequencies
Muneaki Hase, Masayuki Katsuragawa, Anca Monia Constantinescu +1
The coherent modulation of electronic and vibrational nonlinearities in atoms and molecular gases by intense few-cycle pulses has been used for high-harmonic generation in the soft…

Muneaki Hase, Masayuki Katsuragawa, Anca Monia Constantinescu +1
High-order nonlinear light-matter interactions in gases enable generation of x-ray and attosecond light pulses, metrology, and spectroscopy. Optical nonlinearities in solid-state m…
The simplest rout to generating a train of attosecond pulses
Kazumichi Yoshii, John Kiran Anthony, Masayuki Katsuragawa
We report on new routes to generating a train of attosecond pulses. The methods are extremely simple and robust; we need to place only a few thin dispersive materials in the optica…
