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 …

The advent of chirped-pulse amplification in the 1980s and femtosecond Ti: sapphire lasers
in the 1990s enabled transformative advances in intense laser–matter interaction physics …

The generation of power-and wavelength-scalable few optical cycle pulses remains one of
the major challenges in modern laser physics. Over the past decade, the development of …

We demonstrate the generation of 1.1 J pulses of picosecond duration at 1 kHz repetition
rate (1.1 kW average power) from a diode-pumped chirped pulse amplification Yb: YAG …

High-energy phase-stable sub-cycle mid-infrared pulses can provide unique opportunities to
explore phase-sensitive strong-field light–matter interactions in atoms, molecules and solids …

A design for a compact x-ray light source (CXLS) with flux and brilliance orders of magnitude
beyond existing laboratory scale sources is presented. The source is based on inverse …

The milestones of attosecond optics research in the last 15 years are briefly reviewed, and
the latest trends in applications in gaseous and condensed matter are introduced. An …

Sources of short wavelength radiation with femtosecond to attosecond pulse durations, such
as synchrotrons or free electron lasers, have already made possible numerous, and will …

We report on entering a new era of mid-IR femtosecond lasers based on amplification in a
relatively new gain chalcogenide medium, Fe: ZnSe. Our hybrid all-solid-state laser system …

We produce a 3 mJ, two-cycle (11.4 fs), 1 kHz, carrier-envelope phase (CEP)-stable laser
source at 1.7 μm via a three-stage Ti: sapphire-pumped optical parametric chirped-pulse …
