It is well known that a light spot of sub-wavelength will diverge in all directions. In this letter, A method is present......

Our experimental results show that the presence of a proper amount of negative group velocity dispersion is essential to......

A classical ensemble method is used to investigate nonsequential double ionization (NSDI) of Ar atoms irradiated by line......

Temporal properties of random lasing under ultrashort pulse excitation are investigated in a two-dimensional disordered ......

We present a new mechanism of energy gain of electrons accelerated by a laser pulse. It is shown that when the intensity......

We investigate the angular distribution and average kinetic energy of ions produced during ultrafast laser ablation (ULA......

In this work we present experiments by focusing 42 femtosecond laser pulses in air using three different focal length le......

We report the fast lateral photovoltaic effect in pure congruent LiNbO3 crystal induced by pulsed laser and continuous w......

Femtosecond (fs) pulse laser ablation of silicon targets in air and in vacuum is investigated using a time-resolved shad......

A survey on the mechanisms of powerful terahertz (THz) radiation from laser plasmas is presented. Firstly, an analytical......
