UV lasing is studied in nitrogen and the N{sub 2} - SF{sub 6} mixture pumped by a volume discharge initiated by a runaway-electron preionised diffuse discharge (REPDD) produced in an inhomogeneous electric field. It is shown that lasing at a wavelength of 337.1 nm is observed at pressures up to 2.5 atm without any preionisation source. At a pressure of 0.5 atm with the use of blade electrodes and the N{sub 2}:SF{sub 6}=10:1 active medium of length {approx} 6 cm, the output laser energy of {approx} 2 mJ was achieved for the pulse power of 0.55 MW. The REP DD pumping regime is compared with the regime of pumping by a volume discharge produced by a preionisation source. (lasers)
