An efficient supersonic chemical oxygen-iodine laser operating without buffer gas and with simple nozzle geometry Academic Article uri icon


  • We report on an efficient supersonic chemical oxygen-iodine laser, energized by a jet-type singlet oxygen generator, operating without primary buffer gas and applying simple nozzle geometry and transonic mixing of iodine and oxygen. Output power of 177 W with chemical efficiency of 17% was obtained in a 5 cm gain length for Cl 2 flow rate of 11 mmol/s. The power is almost unaffected by water vapor in the medium.
