摘 要:A pulsed gas jet of large size noble gas atomic clusters as targets for high intensity femtosecond laser pulses is reported. The jet can work for gas stagnation pressure in excess of 40 atmospheres and with a repetition rate of 10 Hz to fit 10 Hz table top terrawatt femtosecond Ti∶Sapphire laser. The scaling law indicates that the monomer argon clusters produced in the jet can be as large as 22,000 atoms/cluster at room temperature. Preliminary experiments for argon ionic kinetic energy spectrum indicated that the argon clusters are produced in the jet.
