【 摘 要 】

The spectroscopy of plasma, formed by femtosecond double-pulse laser induced Cu at atmospheric pressure is investigated. The results show that the delay times between the pulses will affect the intensity of spectroscopy. In the range of 1-100 ps, the intensity increased with the delay between the pulses.
