Abstract
Summary form only given. Several studies have shown recently that ultrashort infrared laser pulses propagating through atmosphere may create long plasma filaments. We present an investigation of the nonlinear propagation of ultrashort UV laser pulses in air. We show, for the first time, that it is possible to form connected plasma channels extending over several meters by using as little as 1.7 mJ per pulse having a duration of 450 fs.
