Femtosecond laser filamentation games
PHOTONIC FRONTIERS: LASER FILAMENTATION - Femtosecond pulses create self-guiding filaments. such as laser filamentation. First observed a dozen years ago in a key experiment, filamentation occurs when two nonlinear effects offset each other to trap ultrashort optical pulses in a self-confined filament stretching long distances in air. The influence of laser chirp on the formation of femtosecond laser filamentation in Ar was investigated for the generation of few-cycle high-power laser pulses. The condition for the formation of a single filament has been carefully examined using fs laser pulses with energy over 3 mJ. The filament formation and output spectrum changed very sensitively to the initial laser chirp and gas. Femtosecond Laser Filamentation gives a comprehensive review of the physics of propagation of intense femtosecond laser pulses in optical media (principally air) and the applications and challenges of this new technique.. This book presents the modern understanding of the physics of femtosecond laser pulse propagation, including unusual new effects such as the self-transformation of the pulse Price:
