Y. P. Yuan and J. M. Chen, "Ultrafast dynamics of ionization processes during the formation of subwavelength ripples," Journal of Optical Technology. 83(8), 452-458 (2016). https://doi.org/10.1364/JOT.83.000452
Ultrafast pulses have time durations shorter than or close to the characteristic times of many physical/chemical phenomena, which make it possible to control ionization processes. During femtosecond laser induced subwavelength ripple formation, the control of ionization processes is investigated by a quantum model which considers both the laser wave–particle duality and transient localized changes of material properties. The effects of the fluence and the pulse duration on ionization processes are also discussed. It is found that, by changing the incident fluence and the pulse duration, free electron distributions and the feature sizes of subwavelength ripples can be manipulated.
