TL;DR: In this article, a semiconductor (ZnTe) source is demonstrated, collinearly pumped at an infrared wavelength beyond the three-photon absorption edge and utilizing a contact grating for tilting the pump-pulse front.

TL;DR: In this paper, the authors present an experimental realization of cycle-shaped waveforms and demonstrate control of the HHG process on the single-atom quantum level via attosecond steering of the electron trajectories.

TL;DR: In this article, several methods of carrier-envelope phase stabilization of amplified ultrashort laser pulses are presented, and full temporal characterization of the resultant intense few-cycle light waveforms, reproducible with every laser shot, is achieved by combining conventional pulse characterization techniques with observing the signature of soft-X-ray emission.

TL;DR: In this article, a terahertz time-domain spectroscopy system based on photoconductive components fabricated from low-temperature-grown GaBiAs epitaxial layers and activated by femtosecond 103μm pulses emitted by an Yb:fiber laser is described.

TL;DR: A scheme for parametric amplification that allows to measure the drift of the carrier-envelope phase of the output signal pulses, based on the unique double phase-matching properties of a noncollinearly pumped BBO crystal, which greatly simplifies the single-shot measurement of the phase evolution in Ti:sapphire laser amplifiers.
