Abstract
In recent years great progress has been made on remote generation and detection of THz radiation produced in air by intense femtosecond laser pulses [1, 2]. We present here results showing that it is possible to control the directionality of the Terahertz radiation emitted by two adjacent femtosecond laser filaments formed in air. Calculations for two neighboring filaments predict that the THz emission directionality can be controlled by the delay between the two driven laser pulses.
