Experimental Investigation of Effects on Hot Electron Behaviors for Various Target Parameters

The effects of hot electron generation mechanisms and space behaviors depending on target materials and thickness were studied. At the condition of laser incidence angle with 45°, there are no obvious effects for hot electron generation mechanisms with different target materials, but there are obvious effects on laser absorption efficiency for different target thickness, and hot electron space behaviors do not alter with target thickness, and hot electron emission mainly concentrates on the normal of front and rear surface of targets.
