GAS MONOBLOCK LASER Russian patent published in 1998 - IPC

FIELD: quantum electronics, design of sensors of laser gyroscopes. SUBSTANCE: gas monoblock laser includes power supply source, resonator, body housing mirrors, electrodes, leak-tight current leads to connect power supply source to electrodes, conduit inside resonator body for injection of gas discharge into working zone of cathode and cathode in the form of metal film with oxide layer of surface. Conduit for injection of gas discharge into working zone of cathode has dielectric washer with central hole which diameter satisfies certain relation. Edge of working zone of cathode is moved away from internal surface of dielectric washer by certain distance. Leak-tight current lead is made in the form of aluminum ring with boss that is attached vacuum-tight to resonator body and is shut vacuum-tight by disc. EFFECT: increased functional reliability and efficiency. 2 dwg
