Backward nitrogen lasing actions induced by femtosecond laser filamentation: influence of duration of gain
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 pump-probe measurements. Our findings show that a minimum duration of gain in the excited N _2 molecules is requi...
