Chemical oxygen-iodine laser with a centrifugal spray generator of singlet oxygen

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, O 2 ( 1 Δg), with a high efficiency (chlorine utilization 0.68 - 0.87 and O 2 ( 1 Δg) yield 0.35 - 0.7) even at very high generator pressures (25 - 70 kPa), which cannot be attained by other O 2 ( 1 Δg) generators. This 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 the centrifugal spray generator provided the small signal gain up to 0.5 % cm -1 .
