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 O 2(b 1Σ + g) which is generated through two O 2( 1Δ) energy pooling, we designed and studied a jet singlet oxygen generator with chlorine gas flow rate of 3~10 mmole/s. The O 2( 1Δ) concentration, Cl 2 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 O 2( 1Δ)quenching and H 2O 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.
