Abstract

Summary form only. Several studies have shown recently that ultrashort infrared laser pulses propagating through atmosphere may create long plasma filaments. This effect may have important applications in laser-controlled discharges, long-range deposition of high laser intensities, and new LIDAR monitoring. Here we present an investigation of the nonlinear propagation of sub-picosecond UV laser pulses in air. We show, for the first time, that filamentation is possible with UV laser pulses as well.
