A new discharge type for non-chain pulsed HF/DF laser

KE Chang-jun; TAN Rong-qing; WU Jin; WAN Chong-yi

A new approach has been brought forward to obtain glow discharge in non-chain HF/DF laser.It has been shown a volume discharge is forming in non-uniform electric-field without preionization in SF6 and C2H6 mixtures,the energy deposition up to 200J/L.The discharge in the pin-plane gap is a diffuse jet expanding towards the anode with a bright plasma domain at the cathode.The discharge in the plane-plane gap is presented with many diffuse channels attached to bright circular cathode spots that diverge towards the anode,with the channels overlapping,form a spatially uniform glow discharge.The experimental results indicate that the new discharge type in SF6 and C2H6 mixtures is promising for creation of high energy and high frequency HF/DF laser.
