| 英文摘要 | as efforts continue to elucidate laser-cluster interactions, we investigated the influence of laser wavelength on ion products. in this study, a pulsed methyl iodide cluster was irradiated with a nd-yag nanosecond laser, and the ion products were analyzed using time-of-flight mass spectrometry. multiple-charge atomic ions of cq+ and iq+(q >= 2) were observed using 532 and 1064 nm laser wavelengths; however, only single-charge atomic and molecular ions appeared at 266 and 355 nm. we show that the charge-state distribution for multiple-charge ions is almost independent of laser intensity. a three-stage model was developed to further understand these experimental results: the inverse electron bremsstrahlung heating rate is proportional to the square of laser wavelength, which seems to explain the dependence of multiple-charge ions on the wavelength.
