Transient processes under the interaction between gas laser lights and various targets

Recent research results concerning lasers and the laser ablation of solid and liquid targets are described briefly. The main laser for experiments was KrF laser pumped by an electron beam. The model calculations were performed for the high reprate F2 lasers in mind. An infrared laser and X-ray were taken into account for the model calculations of a space re-entry program and the wall material ablation of an inertial confmement fusion implosion.
