Laser pulse shaping in mid-infrared region and its application for molecular science

Tsubouchi, Masaaki; Momose, Takamasa*

Pulse shaping has been known as one of the essential technologies for coherent control of atoms and molecules. In particular, it has been recently suggested that the manipulation of molecular rovibrational wave packets in the ground electronic state may realize the coherent control of thermal chemical reactions or the quantum gate operation in quantum information processes. The femtosecond pulse shaping in the mid-infrared region is indispensable for this purpose, and has been developed continuously. In this presentation, we demonstrate the precise arbitrary pulse shaping and its characterization of mid-infrared radiation toward rovibrational wave packet manipulation. We have developed the cross-correlation frequency-resolved optical gating (XFROG) as a simple but convenient pulse characterization method in the mid-infrared region.
