METHOD FOR PREPARING ACTIVE MEDIUM FOR OXYGEN- IODINE LASER Russian patent published in 2002 - IPC

FIELD: quantum electronics; chemical process lasers. SUBSTANCE: singlet oxygen undiluted with buffer gas is supplied to mixing zone in the form of small-size transonic jets in parallel with mixing chamber axis. Buffer gas doped with iodine vapors is fed in the form of supersonic high-pressure jets. Their speed ratio is of the order of two. Mixing is effected when pressures in jets at inlet of feebly expanding mixing chamber are equal. EFFECT: enhanced reliability of singlet oxygen producer; reduced cost of laser energy.
