Efficient terahertz radiation generation from air plasma with mid- and near-infrared three-color femtosecond pulses
{{output}}
We report on the generation of the terahertz (THz) radiation from air plasma driven by a three-color femtosecond field with the fundamental pulse in the near- (1700 nm and 800 nm) and mid-infrared (3900 nm) ranges. With an inline optical setup for three-color ... ...
