The cyclic exchange of energy between the pump, signal, and idler fields that characterizes
optical parametric amplification (OPA) places a fundamental limitation on efficiency for …

We introduce a concept for efficient optical parametric amplification (OPA) based on
simultaneously phase-matched idler second harmonic generation (SHG), which together …

An opposite-chirped frequency-domain optical parametric amplification (OC-FOPA) design
is demonstrated and numerically verified. This scheme combines both an ultrabroad …

Optical parametric chirped-pulse-amplification produces two broadband pulses, a signal
and an idler, that can both provide peak powers> 100 GW. In most cases the signal is used …

Parametric interaction allows both forward and backward energy transfers among the three
interacting waves. The back-conversion effect is usually detrimental when unidirectional …

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

We show theoretically that accelerating light beams can be used to manipulate nonlinear
optical processes through spatiotemporal quasi-phase-matching, allowing for …

This study presents a novel way to increase the energy conversion efficiency of optical
parametric amplification by eliminating the idler wave from the interaction using consecutive …

A novel technique for divided-pulse amplification is presented in a proof-of-principle
experiment. A pulse burst, cut out of the pulse train of a mode-locked oscillator, is amplified …

In second harmonic generation, the phase of the optical field is doubled, which has
important implications. Here, the phase-doubling effect is utilized to solve a long-standing …
