| 摘 要： | 用光电流效应,测量了放电正柱中CO_2分子振动能级00~01和10~00的热弛豫速率,研究了热弛豫速率与入射光强、放电电流、气压以及气体组分的依赖关系.求得激光介质中CO_2的热弛豫时间τ_100约0.2～0.8ms,τ_001约0.6～1.5ms.

Investigation on thermal relaxation rates of vibrational levels (0001） and (1000） of CO2 moleculea by OGE |

| Abstract: | The thermal relaxation rates of the vibrational levels (0001) and (1000) of CO2 molecules in a discharged positive .column have been measured by OGE. The dependences of the thermal relaxation rates on the incident intensity, discharge current, pressure and foreign gasea have also been investigated. The approximate values of T001 and T100 obtained are 0.6-1.5 ms and 0.2-0.8 ms respectively. |
