Compact oxygen-iodine laser with a thermally insulated jet singlet–oxygen generator

A compact oxygen-iodine laser without a water vapour trap and with an uncooled jet singlet–oxygen generator was constructed. A laser output power of 150 W was reached when the oxygen preassure at the exit from the jet generator was 25 Torr. The specific power averaged over the oxygen-generator cross section was 10 W cm^-2.
