| 英文摘要 | recently, yao et al. demonstrated the creation of coherent emissions in nitrogen gas with two-color (800 nm + 400 nm) ultrafast laser pulses [j. yao, g. li, c. jing, b. zeng, w. chu, j. ni, h. zhang, h. xie, c. zhang, h. li, h. xu, s. l. chin, y. cheng, and z. xu, new j. phys. 15, 023046 (2013)]. based on this two-color scheme, here we report on systematic investigation of temporal characteristics of the radiation emitted at 391 nm [n-2(+): b-2 sigma(+)(u) (v = 0) -x-2 sigma(+)(g) (v = 0)] by experimentally examining its temporal profiles with the increase of the plasma channel induced by the intense 800-nm femtosecond laser pulses at a nitrogen-gas pressure of similar to 25 mbar. we reveal unexpected temporal profiles of the coherent emissions, which show significant superradiance signatures owing to the cooperation of an ensemble of excited n-2(+) molecules that are coherently radiating in phase. our findings shed more light on the mechanisms behind the coherent laserlike emissions induced by strong-field ionization of molecules. |
