Simulation and Analytical Analysis of the Blumlein Discharge Circuit for the Generation of Coherent UV Pulses in Air
AbstractBlumlein discharge circuit stores electrical energy in its transmission line and can release this energy within a few nanoseconds. This leads the Blumlein to discharge circuit for many applications ranging from electrical discharge in the air to generate nitrogen laser, excitation source for vapor lasers to sub-nanosecond avalanche drivers. In this letter, we have simulated the equivalent Blumlein discharge circuit in Multisimulation and compared the results with the analytical model to have the insight of variations of voltage, current and power in the Blumlein circuit. The Blumlein circuit is divided into spark gap (spark gap) and Blumlein transmission line sections to observe the voltage, current and power oscillations. The rapid oscillations of voltage across the spark gap initiate the discharge in the long transmission lines of Blumlein that generates the coherent UV pulses. This study could pave the way towards the generation of ultraviolet (UV) pulses in the air at the atmospheric pressure.
