Keywords:Aerosol, Fine particles, Laser processing, Decommissioning technology, High speed camera

We are studying a mechanism of aerosol production during a laser processing. We have precisely observed dynamical behaviors and static features of fine particles using a highspeed camera and an electron microscope. We have also performed a model analysis. We will report on the summary of our activity.
