Experimental investigation of the influence of dilutiongas on the O2（a1Δ）yield

The Raman scattering spectrum has been used to measure the yield of singlet oxygen molecules in singlet oxygen generator of COIL. We presented the experimental results on a 0.1 mol/s JSOG. The effect of dilution gas on the yield has been studied. The different dilution gas and different dilution ratio have different efficiency to the delta oxygen yield. For a given COIL device, it is essential to choose suitable dilution gas and dilution ratio.
