Chemical Oxygen-iodine Laser Diluted By Co_2_2 Buffer Gases With A Cryosorption Vacuum Pump

摘要

Experiments were carried out on a verti-chemical oxygen-iodine laser (COIL), which was designed for N_2 and energized by a square-pipe jet singlet oxygen generator (JSOG). A cryosorption vacuum pump was used as the pressure recovery system for CO_2 and N_2 buffer gases. The output power with CO_2 was 27.3% lower than that with N_2, but the zeolite bed showed an adsorption capacity threefold higher for CO_2 than for N_2 in the continuous operation with a Cl_2 flow rate of 155 mmol/s and a total flow rate of 430 ±3 mmol/s.
