混合脉冲IR和VUV laser引起的小团簇表面等离子体共振

Surface plasma resonance in small rare gas clusters by mixing IR and VUV laser pulses

Ch. Siedschlag, J. M. Rost

摘要:

分析了40个原子的氙团簇在激光脉冲泵浦下的电离动力学,其中50 fs的红外激光脉冲与相同长度和峰值强度的真空紫外激光脉冲有一个明确的时间延迟。通过改变脉冲之间的时间延迟,揭示了由于红外激光频率与团簇中准自由电子集体运动频率的一致性而引起的共振能量吸收机制。

英文摘要:

The ionization dynamics of a Xenon cluster with 40 atoms is analyzed under a pum p probe scenario of laser pulses where an infrared laser pulse of 50 fs length follows with a well defined time delay a VUV pulse of the same length and peak intensity. The mechanism of resonant energy absorption due to the coinc idence of the IR laser frequency with the frequency of collective motion of quasi free electrons in the cluster is mapped out by varying the time delay between the pulses.
