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 …

We demonstrate how a scheme called advanced dual-chirped optical parametric
amplification (DC-OPA) that employs two kinds of nonlinear crystal (BiB3O6 and MgO-doped …

The availability of high-energy pulses with durations shorter than the period of their carrier
frequency (sub-cycle) will reveal new regimes of strong-field light–matter interactions …

The advent of self-referenced optical frequency combs, has sparked the development of
novel areas in ultrafast sciences such as attosecond technology, and the synthesis of …

The quest for ever‐shorter optical pulses has been ongoing for over half a century. Although
few‐cycle pulses have been generated for nearly 40 years, pulse lengths below the single …

In recent years, optical parametric chirped-pulse amplification (OPCPA) has emerged as a
powerful tool for the generation of ultrashort pulses with extreme peak intensity. It has …

Phase-locked single-cycle transients with frequency components between 1 and 60 THz
and peak fields of up to 12 MV/cm are generated as the idler wave of a parametric amplifier …

Ultrafast optical parametric amplifiers (OPAs) can provide, under suitable conditions, ultra-
broad gain bandwidths and can thus be used as effective tools for the generation of widely …

One of the most advanced frontiers of ultrafast optics is the control of carrier‐envelope phase
(CEP) ϕ of light pulses, which enables the generation of optical waveforms with …
