ELECTRIC-DISCHARGE OXYGEN-IODINE LASER WITH BUFFER GAS Russian patent published in 2015 - IPC H01S3/95 

FIELD: physics, optics.

SUBSTANCE: invention relates to laser engineering. In an electric-discharge oxygen-iodine laser, in the gas stream directly at the output of a singlet oxygen O₂(¹Δ) molecule generator and before a supersonic nozzle, a gas X (CO₂, SF₆, SiF₄, etc.) is added, the gas consisting of molecules which quench excited ozone $$O_3^{\ast },$$ , with concentration higher than the concentration of O₂(¹Δ) molecules by more than 5×10^-11/k times, where k is the quenching rate constant of the process $$X+O_3^{\ast }\to X+O_3$$ in cm³/s.

EFFECT: higher energy efficiency of the laser.
