Abstract

Nanoparticles are a favorable way to enhance ionization for ultrashort laser pulse focusing on liquid targets. We experimentally investigate how nanoparticles affect the THz generation from deionized water for different concentrations. However, no obvious enhancement is observed comparing with the signal from deionized water under the same excitation condition. Thus, the concentration of nanoparticles is not a crucial factor to enhance THz wave generation within the order of 10^8~10^11 particles/ml. We believe our results provide useful information on enhancing the liquid THz emission source by nanoparticles
