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:

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: Nov 01,  · We show experimentally that an embarked terawatt femtosecond laser can significantly decrease this drag. We measured a 50% transient reduction of drag on a test model placed in a supersonic wind tunnel at Mach 3. This effect was initiated by the thin hot air column created in front of the supersonic object by filamentation of the laser area907.info: P.-Q. Elias, N. Severac, J.-M. Luyssen, Yves-Bernard André, I. Doudet, B. Wattellier, J.-P. Tobeli. Powerful femtosecond laser pulses propagating in transparent materials result in the formation of self-guided structures called filaments. Such filamentation in air can be controlled to occur at a. 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. Multiple refocusing of intense femtosecond laser pulses in air was studied both experimentally and numerically. Using fluorescence measurement and acoustic diagnostics simultaneously, filamentation and multiple refocusing of laser pulses were area907.info: Lanzhi Zhang, Tingting Xi, Zuoqiang Hao. Femtosecond Lasers Extend Glass Cleaving to Mixed Materials Published on 9 January Filamentation cutting is a relatively new process that uses ultrafast lasers to cut a wide range of glass substrates, from soft borosilicates to chemically hardened glass used in smartphone displays.

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. Powerful femtosecond laser pulses propagating in transparent materials result in the formation of self-guided structures called filaments. Such filamentation in air can be controlled to occur at a distance as far as a few kilometers, making it ideally suited for remote sensing of pollutants in the atmosphere. On the one hand, the high intensity inside the filaments can induce the fragmentation Cited by: This book attempts to give a discussion of the physics and current and potential applications of the self-focusing of an intense femtosecond laser pulse in a tra- parent medium. Although self-focusing is an old subject of nonlinear optics, the consequence of self-focusing of intense femtosecond laser pulses is totally new and unexpected. Dec 23,  · Powerful femtosecond laser pulses propagating in transparent materials result in the formation of self-guided structures called filaments.

A pattern within the large cell matches the. femtosecond laser radiation to cause the condensation of fog droplets out of Phenomena related to filamentation of laser beams were observed only a matches an electronic or dipole-active vibrational transition of the aerosol substance. A proof‐of‐concept of space‐borne laser filamentation for different curvatures ( , , km) for femtosecond infrared ( nm) pulses. This book attempts to give a discussion of the physics and current and potential applications of the self-focusing of an intense femtosecond laser pulse in a tra-. Shortly afterwards, filamentation of femtosecond laser pulses was shown to waves (Faccio et al., ), whose group velocity matches.
