Abstract

We have studied for the first time the simultaneous generation of terahertz and X-ray radiation from noble gas based nano-cluster supersonic jet under “one-” and “two-color” (fundamental and its second harmonic) excitation with high-power femtosecond laser pulses. It was shown that optimal conditions for effective generation of terahertz and X-ray radiation are different. That makes possible efficiently control the magnitudes of terahertz and X-ray signals simultaneously generated from gas nano-cluster jet. Controlling could be provided by different means: by varying of time delay between laser pulse and cluster jet formation moment, or by varying of chirp parameter of laser pulses. Also we shown that efficiency of THz generation from cluster jet could be effectively controlled by varying of ratio between clustered and buffer (carrier) gases in mixture. Angular distribution of terahertz beam generated near by optical axis under “two-color” laser excitation conditions has been measured as well.
