This analysis reveals how energy and pressure affect second harmonic generation in air, suggesting optimal conditions for efficiency.
In this paper generation of the second harmonic during filamentation of femtosecond laser pulses in air is studied. Analyzing the spatial and spectral characteristics of the second harmonic, we identify key factors affecting its generation, including the energy of the laser pulse, focusing conditions, and air pressure. Numerical investigations confirm experimental observations, showing the efficiency of second harmonic generation ~10−10.
