The development of ultrafast laser techniques has provided a novelty tool for physics, chemiistry, biology and material science to study the ultrafast dynamic process. It is also important for the hightechnique, such as ultrafast optical communication, molecular biology and genetic engineering. The development of femtochemistry is presented, including controlling the reaction by optimal shaped pulse, femtosecond phase-coherent two-dimensional spectroscopy, and spatiotemporal coherent control of lattice vibration waves.
