| 英文摘要 | we experimentally investigate generation of backward 357 nm n-2 laser in a gas mixture of n-2/ar using 800 nm femtosecond laser pulses, and examine the involved gain dynamics based on pumpprobe measurements. our findings show that a minimum duration of gain in the excited n-2 molecules is required for generating intense backward nitrogen lasers, which is similar to 0.8 ns under our experimental conditions. the results shed new light on the mechanism for generating intense backward lasers from nitrogen molecules, which are highly in demand for high sensitivity remote atmospheric sensing application. |
