Abstract

We used both the backscattered nitrogen fluorescence signal (BSF) and ICCD fluorescence side imaging methods to study the filament light intensity with a 4 J/60 fs Ti:sapphire laser beam. It has been concluded that even the laser power is increased by 100 times in our experiment the peak laser intensity in the filament only has a little change. We attribute this phenomenon to the result of intensity clamping and the competition of multiple filaments.
