Paper Abstract

Terahertz wave generation from air plasma induced by ultrashort laser pulses has been widely studied in the past decade. We report the study of terahertz wave generation from the laser induced plasma where there is a preformed air plasma. We found that the power of the terahertz wave generated by the main pump pulse decreases in the presence of the preformed plasma. The amount of the power drop increases with the power of pulse that generates preformed plasma. The result confirms the key role of tunneling ionization in the terahertz generation mechanism.
