The influence of cross-phase modulation on third-harmonic generation is theoretically
studied. Generalized phase-matching conditions for third-harmonic generation including …

We show, for the first time to our knowledge, that the fundamental beam that participates in
the process of third-harmonic generation experiences an additional high-order nonlinear …

Unlike third-harmonic generation in a monochromatic field, which gives rise to a signal at the
frequency 3omega0, with omega0 being the frequency of the pump field, a broadband …

We experimentally demonstrate simultaneous phase and group velocity locking of
fundamental and generated second harmonic pulses in Lithium Niobate, under conditions of …

A simple technique for generating trains of ultrafast pulses is demonstrated in which the
linear separation between pulses can be varied continuously over a wide range. These …

We study two-color high-order harmonic generation using an intense driving field and its
weak second harmonic, crossed under a small angle in the focus. Employing sum-and …

We experimentally demonstrate third-harmonic generation (THG) by intense femtosecond
laser pulse at a central wavelength of∼ 800 nm superposed by its second harmonic in air …

Attosecond double-pulse (twin-pulse) production in high-order harmonic generation is
manipulated by a combination of two-color and carrier-envelope phase-control methods. As …

We have experimentally investigated the frequency modulation of high-order harmonics in
an orthogonally polarized two-color laser field consisting of a mid-infrared 1800nm …

We present evidence for self-stabilization of the relative spectral phase of high-order
harmonic emission against intensity variations of the driving field. Our results demonstrate …
