AbstractA near-infrared femtosecond laser pulse produces laserlike coherent radiation from singly ionized Formula Presented molecules when it experiences filamentation in air or pure nitrogen, and the lasing radiation reaches maximal intensity when the driving pulse is slightly polarized elliptically. Based on a strong-field transient ionization model that considers ionization-induced quantum coherence, we reproduced the general feature of this counterintuitive dependence of the lasing intensity on pump laser ellipticity by numerically solving the Maxwell-Bloch equations of the lasing amplification process. The simulation results suggest that the competition effect between the increase of Formula Presented inversion probability and the decrease of overall Formula Presented ion production with the increasing ellipticity is mainly at the origin of observed ellipticity dependence. Additionally, the simulation predicts that ionization-induced quantum coherence also exhibits a nonzero ellipticity dependence and plays a nontrivial role in the weakly seeded and self-seeded scenarios. Our findings suggest that controlling the ionization-induced coherence could be a promising approach to improve the Formula Presented lasing generation. © 2023 American Physical Society.
