We give a full description of a state-of-the-art femtosecond transient spectrometer. The setup
has been put together under full consideration of all technical and conceptual developments …

We report on the spectral broadening of∼ 1 μ J 30 fs pulses propagating in an Ar-filled
hollow-core photonic crystal fiber. In contrast with supercontinuum generation in a solid-core …

We demonstrate a simple scheme to generate 0.4 mJ 11.5 fs laser pulses at 1.8 μ m⁠.
Optical parametrically amplified pulses are spectrally broadened by nonlinear propagation …

We present a new method to broaden the amplification range in optical parametric
amplification toward the bandwidth needed for single cycle femtosecond pulses. Two-color …

We report the generation of extremely broadband and inherently phase-locked mid-infrared
pulses covering the 5 to 11 µm region. The concept is based on two stages of optical …

A noncollinearly phase-matched optical parametric amplifier pumped by a commercial 2

Diffraction and microscopy with ultrashort electron pulses can reveal atomic-scale motion
during matter transformations. However, the spatiotemporal resolution is significantly limited …

Femtosecond laser pulses, which are tunable from 440 to 990 nm, are generated at MHz
repetition rates by noncollinear parametric amplification (NOPA). The pulses have durations …

Spectral phase interferometry for direct electric-field reconstruction has become a standard
technique for the measurement and characterization of extremely short laser pulses. Here …

The beam attenuation by two-photon absorption in thin crystals and glass plates is utilized
for directly measuring the intensity autocorrelation of UV femtosecond pulses without the …
