Photoelasticity images of pulsed laser ablation in water and in air were simulated by Finite Element Method. In the paper "Compare transient stress induced in in-air and in-water laser ablation using simulation method", the Von Mises stress distribution in the target is deduced from the simulated images and is compared between the two-ablation regimes. The result confirms that pulse laser ablation in the water can induced a stress about 100 times higher than that induced in ablation in the air.
