Abstract :
In THz wave generation in air plasmas induced by laser pulses composed of fundamental and second-harmonic waves, we introduced a prepulse, 0-2 ns before the main pulse. The prepulse suppressed the THz wave generated by the main pulse. We analyzed the suppression factor as a function of time-delay.
