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.
