Some features of discharge initiation in vacuum gap by optical range radiation
Keyword(s):
The hypothesis of discharge initiation in vacuum gap by optical range radiation based on pre-viously obtained experimental data. During the laser pulse interaction withelectrode erosionproductsthe glow discharge has ignited. In result of ionization-overheating instability the dis-charge has had current channel contraction and has transferred to arc. Thedependences ofmaterial of target thermo dynamical parameters on theminimal and thresholdlaser pulse en-ergyhave demonstrated. The threshold laser pulse energy –the energy which enough to effec-tive impact on the laser plasma.
