We present the results of experimental and theoretical study of interaction of intense femtosecond laser pulses with gas cluster beam aimed to the generation of terahertz (THz) and x-ray emission. Clusters ware produced by partial condensation of various gases during their expansion through a conical nozzle into vacuum:pure Ar, mixtures CF2Cl2+He, Ar+He etc. We analyze the use of two laser pulse excitation schemes in our experiments, single- and two-color geometries (fundamental frequency mixed with its second harmonic) for the generation of high power terahertz (THz) radiation.
