Fast chemical reactions that cannot be identified by eye become observable by utilizing strobe light. The time resolution of the flash photolysis was limited by the nanosecond time duration of the discharge flash lamp. After the development of femtosecond laser, it has been widely applied to observe transition state of various chemical reactions. In near-infrared region, commercial light source of Ti/sapphire laser is available as femtosecond light source, but not available in visible and ultraviolet regions. In this chapter, we report our development of sub-10fs visible-NIR, UV, and DUV pulses and their applications to ultrafast spectroscopy.
