A chemical oxygen-iodine laser driven by the centrifugal spray generator of singlet oxygen was developed and experimentally studied. Modeling and experimental studies showed that the designed generator can produce singlet oxygen (SO) with a high efficiency (chlorine utilization 0.68-0.87 and SO yield 0.35-0.7) even at very high generator pressures (25-70 kPa), which cannot be attained by other SO generators. The high-pressure operation should be beneficial for a pressure recovery system of the laser. Another specific feature of the generator is a very high BHP utilization (0.24-0.6). The developed separator can effectively remove even small droplets (>1 µm) from gas at the generator exit. Preliminary experiments on the COIL driven by the centrifugal spray generator provided the small signal gain up to 0.5 % cm-1.
