Few methods can produce orbital angular momentum beams in the extreme ultraviolet or X-ray, and controlling orbital angular momentum on these beams remains challenging. Here the authors apply wave mixing to a tabletop high-harmonic source and control

We investigate the triggering and guiding of DC high-voltage discharges over a distance of 37 cm by filaments produced by ultraviolet (266 nm) laser pulses of 200 ps duration. The latter reduce the breakdown electric field by half and allow up to 80%

A near-infrared laser generates gain on transitions between the $B^{2}\mathrm{\ensuremath{\Sigma}}_{\text{u}}^{+}$ and $X^{2}\mathrm{\ensuremath{\Sigma}}_{\text{g}}^{+}$ states of the nitrogen molecular cation in part by coupling the $X^{2}\mathrm{\e

We demonstrate a novel method to measure the temporal electric field evolution of ultrashort laser pulses. Our technique is based on the detection of transient currents in air plasma. These directional currents result from subcycle ionization of air

Air lasing in the nitrogen molecular ion is not well understood because the complex physics responsible for gain is interwoven with pulse propagation in an extreme environment. Here we use a short gas jet to limit the interaction length, thereby remo

A factor of 2 enhancement of the sensitivity of a mode-locked laser gyroscope is experimentally demonstrated. This enhancement is achieved through a resonant dispersion applied to all modes of the frequency comb.

Traditional N+ lasing experiments are limited because the pump pulse combines ionization with excitation of the gain medium. A second excitation pulse can act independent of ionization to control electronic, vibrational, and rotational dynamics.

Using a streak camera, we measure the spatial profile of fluorescence emission of from a filament in air. The delay is inversely proportional to the density of the excited states contributing in collective emission.
