Recent progress in high power ultrafast short-wave and mid-wave infrared lasers has
enabled gas-phase high harmonic generation (HHG) in the water window and beyond, as …

Contemporary ultrafast science requires reliable sources of high-energy few-cycle light
pulses. Currently two methods are capable of generating such pulses: post compression of …

Attosecond metrology has so far largely remained limited to titanium: sapphire lasers
combined with an active stabilization of the carrier-envelope phase (CEP). These sources …

Recently two emerging areas of research, attosecond and nanoscale physics, have started
to come together. Attosecond physics deals with phenomena occurring when ultrashort laser …

The generation of extremely short isolated attosecond pulses requires both a broad spectral
bandwidth and control of the spectral phase. Rapid progress has been made in both …

The generation of sub‐optical‐cycle, carrier–envelope phase‐stable light pulses is one of
the frontiers of ultrafast optics. The two key ingredients for sub‐cycle pulse generation are …

Today's ultrafast lasers operate at the physical limits of optical materials to reach extreme
performances. Amplification of single-cycle laser pulses with their corresponding octave …

We report on the first table-top high-flux source of coherent soft x-ray radiation up to 400 eV,
operating at 1 kHz. This source covers the carbon K-edge with a beam brilliance of …

We produce 1.5 cycle (10.5 fs), 1.2 mJ, 3 kHz carrier-envelope-phase-stable pulses at 2.1
μm carrier wavelength,<? A3B2 show [pmg: line-break justify=" yes"/]?> from a three-stage …

By employing pulse compression with a stretched hollow-core fiber, we generated 2-cycle
pulses at 1.8 μm (12 fs) carrying 5 mJ of pulse energy at 100 Hz repetition rate. This energy …
