Femtosecond laser direct writing is a powerful technique for fabricating micro‐nano devices
as it can modify the interior of transparent optical materials in a spatially selective manner …

The petawatt (PW) laser has experienced a rapid development in the past two decades, and
tens of giant facilities have been constructed worldwide. After realizing 10–100 PW, it seems …

The temporal characterization of ultrafast laser pulses has become a cornerstone capability
of ultrafast optics laboratories and is routine both for optimizing laser pulse duration and …

The electric field of an ultrashort laser pulse often fails to separate into a product of purely
temporal and purely spatial factors. These so-called spatio-temporal couplings constitute a …

A laser system producing controllable and stable pulses with high power and ultrashort
duration at high repetition rate is a key component of a high energy laser-plasma accelerator …

An object that possesses chirality, that is, having its mirror image not overlayed on itself by
rotation and translation, can provide a different optical response to a left-or right-handed …

An overview of recent achievements in the field of femtosecond laser writing in transparent
materials is presented. Thanks to the unique properties of light–matter interaction on the …

Optical rectification of femtosecond laser pulses has emerged as the dominant technique for
generating single-and few-cycle terahertz (THz) pulses. The advent of the tilted pulse front …

We present a rigorous, but mathematically relatively simple and elegant, theory of first-order
spatio-temporal distortions, that is, couplings between spatial (or spatial-frequency) and …

Single femtosecond laser beam induced nanograting structure in transparent media has
attracted extensive attention in many fields of science and technology in the past decades …
