GAS-DYNAMIC LASER Russian patent published in 2008 - IPC H01S3/22 

FIELD: electronics.

SUBSTANCE: invention is related to quantum electronics and is intended for creation of powerful laser installation that operates on combustion products. Substance: gas-dynamic laser contains control system, gas-dynamic duct for pumping of working medium, sources of the main consumed components of working medium, source of fuel, remotely controlled stop devices. At that at the outlet of gas-dynamic duct gate valve is installed with connection and disconnection circuits. Systems of heat exchanger heating are equipped with pressure relays, which are installed in pipelines of oxidant supply and heating system fuel supply, accordingly, between sources of oxidant and fuel and heat exchangers. Control system includes individual units of heat exchanger heating automatics with connection and disconnection circuits. At that every unit is equipped with ignition device with connection and disconnection circuits, ignition detectors and time delay devices. Besides, casing of every heat exchanger is equipped with temperature detectors, and pressure relays are provided in pipeline of cooling agent supply. Besides, interlocks are introduced in circuit of heating system automatics unit connection and circuit of ignition device connection.

EFFECT: higher safety and operation reliability.
