TL;DR: Along with nanosecond filament-induced flashes at both polarities, long, about a half microsecond, corona flashes were observed at the negative polarity.

Highly enhanced terahertz conversion by two-color laser filamentation at low gas pressures
TL;DR: The pressure-dependent study reveals an anticorrelation between terahertz output energy and local plasma fluorescence brightness, which determines the absolute phase difference between two-color laser fields for maximal terAhertz generation, as well as verifies the microscopic mechanism of tera hertz generation in two- color laser mixing.

TL;DR: In this article, the femtosecond laser facility T&T (terawatt & terahertz) of DRDC-Valcartier was used to detect trace methane gas remotely in an open field atmosphere during daytime (with strong sun light) using filament-induced fluorescence spectroscopy.
Journal ArticleDOI
Higher-order Kerr effect and harmonic cascading in gases.
TL;DR: Cascading contributions to the nonlinear HOKE coefficients in gases are studied to show how the observed saturation of the HOKE nonlinearity could lead to filamentation of femtosecond pulses in gases without plasma playing an active role.

Plasma perspective on strong field multiphoton ionization.
TL;DR: During strong-field multiphoton ionization, a wave packet is formed each time the laser field passes its maximum value, and one important parameter which determines the strength of these effects is the rate at which the wave packet spreads in the direction perpendicular to the laser electric field.
