CHEMICAL ELEMENT VAPOR PULSE-PERIODIC LASER Russian patent published in 2005 - IPC

FIELD: quantum electronics; production of chemical-element vapor pulse-periodic lasers.

SUBSTANCE: proposed laser has gas-discharge tube, high-voltage rectifier, resonant charging choke, charging diode, storage capacitor, thyratron, generator, feed-through capacitor, negative bias source, and power supply. Gas-discharge tube is placed in cavity. High-voltage rectifier is coupled through one of its outputs witch input of resonant charging choke. Generator output is electrically connected via feed-through capacitor to gate electrode that functions as thyratron grid. Negative bias source is connected to gate electrode. High-voltage rectifier is coupled through its other output with storage capacitor. Second lead of the latter is connected through charging diode to output of resonant charging choke. Common generator output is connected to thyratron cathode. Thyratron anode is electrically connected to storage capacitor and to charging diode. Thyratron cathode is coupled with gas-discharge tube anode and has decoupling filter and two storage capacitors. Decoupling filter is made in the form of two inductance coils.

EFFECT: facilitated measurement of excitation pulse power characteristics, optimized active medium pumping parameters, enhanced electric safety.
