We are studying a mechanism of aerosol production during a laser cutting for fuel debris retrieval. We precisely observe dynamical behaviors of plume and fine particles produced from irradiate samples made of metal, ceramics and concreate using a high power fiber laser. We precisely observe records taken by two high speed cameras. We will report on the summary of the observations.
