Strong terahertz emission from relativistic laser-solid interactions
Terahertz radiation has been attracted much interest due to increasingly wide applications.Though THz radiation can be generated with various ways,it is still a big challenge to obtain strong tabletop sources.Plasmas,with an advantage of no damage limit,are promising medium to generate strong THz radiation.THz radiation from femtosecond laser-induced plasma filaments in low density gases has been reported.However,the radiation is found to be saturated with pump laser energy.Intense laser-solid interactions,in which high laser intensity (up to 1019-20W/cm2) can be applied,are expected to generate stronger THz sources .
