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 …

We demonstrate a compact 20? Hz repetition-rate mid-IR OPCPA system operating at a
central wavelength of 3900? nm with the tail-to-tail spectrum extending over 600? nm and …

Over the past decade intense laser fields with a single-cycle duration and even shorter,
subcycle multicolour field transients have been generated and applied to drive attosecond …

High harmonic generation (HHG) using waveform-controlled, few-cycle pulses from Ti:
sapphire lasers has opened emerging researches in strong-field and attosecond 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 …

This is a review of some recent development in femtosecond filamentation science with
emphasis on our collective work. Previously reviewed work in the field will not be discussed …

Femtosecond laser filamentation is a unique nonlinear optical phenomenon when high-
power ultrafast laser propagation in all transparent optical media. During filamentation in the …

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 …

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 …
