laser场中的小稀有气体团簇:长和短laser波长下的电离和吸收
Small rare gas clusters in laser fields: ionisation and absorption at long and short laser wavelengths
摘要:
本文用一个微观的、半经典的模型研究了短脉冲激光与稀有气体团簇的相互作用。场和碰撞电离以及重组被纳入自洽,使这些过程的使用率可以避免。分析了团簇在近红外(800nm)和真空紫外(100nm)波段的激光吸收和电离机制。
英文摘要:
The interaction of short laser pulses with small rare gas clusters is investigated by using a microscopic, semi-classical model with an explicit treatment of the inner-atomic dynamics. Field and collisional ionisation as well as recombination are incorporated self-consistently so that the use of rates for these processes could be avoided. The laser absorption and ionisation mechanisms in clusters at near-infrared (800nm) and VUV wavelength (100nm) are analysed.
