| 中文摘要 | using time-of-flight spectrometry, the interaction of intense femtosecond laser pulses with argon clusters has been studied by measuring the energy and yield of emitted ions. with two different supersonic nozzles, the dependence of average ion energy (e) over bar on cluster size (n) over bar in a large range of (n) over bar approximate to 3 x 10(3) similar to 3 x 10(6) has been measured. the experimental results indicate that when the cluster size (n) over bar <= 3 x 10(5), the average ion energy (e) over bar proportional to (n) over bar (0.5), coulomb explosion is the dominant expansion mechanism. beyond this size, the average ion energy gets saturated gradually, the clusters exhibit a mixed coulomb-hydrodynamic expansion behavior. we also find that with the increasing gas backing pressure, there is a maximum ion yield, the ion yield decreases as the gas backing pressure is further increased. |
