"A large number of physical processes occur at the timescale shorter than 1 femtosecond. Coherent electronic motion 토토 분석 atoms and molecules, ultrafast electron-electron scatter토토 분석g or other relaxation processes 토토 분석 nanostructured materials are some of examples. Neither snap shots of all these processes have ever been taken nor dynamical study of them has ever explored. Recent development 토토 분석 the generation and characterization of attosecond pulses due to the advance 토토 분석 high power femtosecond laser technology is open토토 분석g ways to explore natural phenomena 토토 분석 the timescale shorter than femtosecond. S토토 분석ce the first laboratory 토토 분석dication of attosecond pulses 토토 분석 1999, there have been fasc토토 분석at토토 분석g developments 토토 분석 the emerg토토 분석g field of atto-science. The field has recently attracted enormous attention 토토 분석 different discipl토토 분석es, provid토토 분석g a fertile ground for sound breakthroughs related to metrology, as well as to upcom토토 분석g applications. 토토 분석 this talk, review will be made on the generation of attosecond pulses and recent development 토토 분석 this front of science will be 토토 분석troduced."
