• We have succeeded for the first time to simulate dynamic phase transition from metal to vapor. This success is due to the CIP method that can treat solid, liquid and gas together and can trace a sharp interface with almost one grid. The code is applied to the formation of crater under the illumination of a short pulse laser. The crater size created by 650mJ laser in 8nsec agrees well with the simulation including an elastic-plastic effect and its depth is 100μm which corresponds to anomalously large cutting speed of 10^6cm/sec for 8ns pulse. However, the simulation demonstrates that evaporation is caused by remnant hot gas during several 100ns and occurs in the direction of 75 degree in an intermittent and unstable manner leading to a unique explanation on the angular distribution of debris. Some example of three-dimensional simulations are also presented.
