Investigation of enhanced second harmonic generation in laser-induced air plasma
Shing Yiu Fu, Kareem J. Garriga Francis, Mervin Lim Pac Chong +2
We report a systematic investigation into the processes behind a near hundredfold enhanced second harmonic wave generated from a laser-induced air plasma, by examining the temporal…
