METHOD OF EXCITING PULSED INDUCTIVE-CAPACITIVE LONGITUDINAL DISCHARGE IN GAS MEDIA AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2011 - IPC H01S3/09 

FIELD: physics.

SUBSTANCE: method involves exciting an active gas medium with transverse inductive discharge generated by an alternating magnetic field in an inductor for excitation with high-voltage pulses which simultaneously generate, in the part of the tube with unexcited gas medium, an electric vortex discharge with eddy current flowing in the direction parallel to the optical axis of radiation. Pulses are transmitted with amplitude which is higher than breakdown potential U_br of the active gas medium, duration not more than 100 ns, where duration of the rising front of the voltage pulse τ_f ≤ 30 ns. Total inductance of the circuit for exciting transverse inductive discharge is less than total inductance of the circuit for exciting inductive-capacitive longitudinal discharge. The device for realising said method includes capacitive pumping generator connected to an exciting inductor, consisting of n parallel-connected solenoids which are wound on a dielectric tube containing an active gas mixture. There is a flat dielectric mirror on one side of the tube and there are quoting units on its ends with plane-parallel plates made from quartz. In one of the units there is hollow cathode. Total inductance of the exciting inductor satisfies the condition On each solenoid of the inductor, there are m ≤ 20 windings of a copper bus with winding pitch of W/5, where W is the width of the bus. The common winding of the exciting inductor wire is connected to the return wire and is earth with cathode of the adjustment unit.

EFFECT: broader functional capabilities and improved operational characteristics.
