  • So far, metastable Singlet oxygen is the only electronic excited state molecule that can be efficiently produced simply by a chemical reaction. To examine the proposal for a chemical laser of near-visible range by using the higher excited state oxygen O2 (b1Σ) which is generated through two O2 (1△) energy pooling, we de signed and studied a jet singlet oxygen generator with chlorine gas flow rate of 3-10 mmole/s. The O2(1△) concentratron, Cl, utilization rate and water content are measured using different injectors at different chlorine flow rate, cold trap temperature. We find that the optimum cold medium temperature is -140℃ to -150℃ when the trap is made of PVC.

In optimum conditions, the water vapor pressure in the gas output can be reduced to as low as 4 Pa, which is reported for the first time.

Abstract: So far, metastable Singlet oxygen is the only electronic excited state molecule that can be efficiently produced simply by a chemical reaction. To examine the proposal for a chemical laser of near-visible range by using the higher excited state oxygen O2 (b1Σ) which is generated through two O2 (1△) energy pooling, we de signed and studied a jet singlet oxygen generator with chlorine gas flow rate of 3-10 mmole/s. The O2(1△) concentratron, Cl, utilization rate and water content are measured using different injectors at different chlorine flow rate, cold trap temperature. We find that the optimum cold medium temperature is -140℃ to -150℃ when the trap is made of PVC. This result is explained by the competition between O2(1△) quenching and H2O freeze on wall of the trap. In optimum conditions, the water vapor pressure in the gas output can be reduced to as low as 4 Pa, which is reported for the first time.
