چکیده
We present direct time- and space-resolved measurements of the electron density of femtosecond laser pulse-induced plasma filaments. The dominant nonlinearity responsible for extended atmospheric filaments is shown to be field-induced rotation of air molecules.

The study of propagation of a femtosecond laser pulse in the breast tissue
In this paper, the evaluation of time profile of a femtosecond pulse laser propagated through biological tissues is studied. The majority of the biological tissues with a high scattering anisotropy must be considered as turbid media, that their optical responses are complicated. To study the propagation of ultra-short pulse in turbid media, the diffuse equation is used. In this study, the analy...
متن کاملGeneration of extended plasma channels in air using femtosecond Bessel beams.
Extending the longitudinal range of plasma channels created by ultrashort laser pulses in atmosphere is important in practical applications of laser-induced plasma such as remote spectroscopy and lightning control. Weakly focused femtosecond Gaussian beams that are commonly used for generating plasma channels offer only a limited control of filamentation. Increasing the pulse energy in this cas...
متن کاملOptical breakdown of air triggered by femtosecond laser filaments
Experiments on gas breakdown by powerful optical pulses date back to the early days of lasers. The following development resulted in the generation of dense plasma columns up to several tens of meters in length. Pulsed neodymium-glass and CO2 lasers used in these demonstrations had pulse energies of several hundred Joules. Optical breakdown with high-energy nanosecond (or longer) laser pulses i...
متن کاملبررسی نوع چرپ القایی و اثر آن بر دامنه میدان عقبه در انتشار تپ لیزر در کانال پلاسما
In this paper, the propagation of a Gaussian and femtosecond laser pulse through a plasma channel is considered and the amount of induced chirp, as well as it’s type, on laser pulse frequency has been investigated. The group velocity dispersion (GVD) and relativistic effects has been taken into account in propagation equations. It is concluded that the relativistic effect induces positive chirp...

Backgrounds/aims: To evaluate treatment with high peak power pulse energy by femtosecond ultrashort pulse laser (titanium sapphire laser) delivered at an 800 nm wavelength for corneal neovascularisation using photodynamic therapy (PDT) mediated by indocyanine green (ICG). Methods: Using a gelatin solid as an in vitro corneal model, the safety of laser power was studied to determine if it degene...
