SPACE-SAVING PULSED GAS LASER AND MAGNETIC PULSE COMPRESSING DEVICE FOR ITS EXCITATION Russian patent published in 2005 - IPC

FIELD: pulsed gas lasers excited by fast longitudinal discharge in second positive set of molecular nitrogen streaks.

SUBSTANCE: proposed laser has coaxial sectionalized discharge cell forming low-inductance power transmission line with pulse shaping circuit connected to central electrode, and thyratron placed in conducting shell which is part of common low-inductance power transmission line. Pulse shaping circuit made in the form of magnetic pulse compressing device has saturating reactors inductively and capacitively coupled with discharge tube mounted in magnetic pulse compressing device. Laser has coaxial sectionalized discharge cell with gas gap between plates. Gas gap thickness to discharge tube wall thickness ratio is higher than dielectric constant of discharge tube material. Sheet-steel ballast capacitors are disposed coaxially to discharge cell and symmetrically to magnetic pulse compressing device. The latter uses parallel circuit arrangement for connecting magnetic compression power lines. Each line incorporates additional saturating reactor in first section. Parallel-connected to ground are limiting saturating reactor and peaking capacitor.

EFFECT: enhanced life in sealed-off condition, increased repetition rate without forced cooling and specific pulse power; reduced electromagnetic noise.
