主　　题：Solid laser interaction 

摘      要：Epoxylite,polymethylmethacrylate and aluminum are irradiated by a cw CO2 laser and their temperature fluctuations are measured by the infrared thermal imagers. It is reported that the temperature fluctuation becomes stronger with increase of the laser-solid interaction time in the experiment, which is in good agreement with the theory prediction. Furthermore, the temperature fluctuation is experimentally studied while the material is melted or vaporized.
