英文摘要a 2-kw-class chemical oxygen-iodine laser (coil) using nitrogen buffer gas has been developed and tested since industrial applications of coil devices will require the use of nitrogen as the buffer gas. the laser, with a gain length of 11.7 cm, is energized by a square pipe-array jet-type singlet oxygen generator (spjsog) and employs a nozzle bank with a designed mach number of 2.5. the spjsog has advantages over the traditional plate-type jsog in that it has less requirements on basic hydrogen peroxide (bhp) pump, and more important, it has much better operational stability. the spjsog without a cold trap and a gas-liquid separator could provide reliable operations for a total gas flow rate up to 450 mmol/s and with a low liquid driving pressure of around 0.7 atm or even lower. the nozzle bank was specially designed for a coil using nitrogen as the buffer gas. the cavity was designed for a mach number of 2.5, in order to provide a gas speed and static temperature in the cavity similar to that for a traditional coil with helium buffer gas and a mach 2 nozzle. an output power of 2.6 kw was obtained for a chlorine flow rate of 140 mmol/s, corresponding to a chemical efficiency of 20.4%. when the chlorine flow rate was reduced to 115 mmol/s, a higher chemical efficiency of 22.7% was attained. measurements showed that the spjsog during normal operation could provide a singlet oxygen yield y greater than or equal to 55%, a chlorine utilization u greater than or equal to 85%, and a relative water vapor concentration w = [h2o]/([o-2] + [cl-2]) less than or equal to 0.1.
