摘要：

This paper reports the formation of low-energy low-divergence pulsed indium atomic beam via ablation of thin film by illumination from the rear side with second harmonic of Q-switched Nd:YAG laser under high vacuum (similar to 10(-5) Torr). Angular divergence of ablated indium atomic, reflectivity Modulation of thin film due to ablation. and longitudinal atomic velocity of ablated beam were studied as a function of laser fluence. Atomic force microscope scans of the deposited multiple Shots Of Pulsed atomic beams show the formation of "nano-hills."
