| 内容記述 | Advances in physical studies and high-power laser technologies enabled us to realize the laboratory-size laser-driven plasma based soft x-ray lasers (SXRLs). We have examined ablation/damage phenomena for dielectric, insulator, metal materials and multilayer optics by use of the picosecond SXRL pulses. It was confirmed that morphologies of ablation structures strongly depended on the sample materials. Damage thresholds and modification structures obtained by the picosecond SXRL provide the same results by the femtosecond SXFEL. This means that picosecond SXRL irradiation experiments can give a good benchmark for femtosecond SXFEL irradiation experiments. However, the SXRL is a self-amplified spontaneous emission laser source, so that the shot-by-shot output energy has a relatively large fluctuation. Recently, we have developed the SXRL beamline equipped with an intensity monitor in order to correct accurate energy values during the irradiation experiment. We will present the recent achievements of ablation studies obtained by the newly constructed SXRL beamlines. | |||||
