Abstract: This paper represents the measuring principle of the solid rapid thermal strain induced by high intensity laser light using temperature compensation resistance strain gauges, and introduces measurements of aluminium alloy exposed to a high intensity CW-CO2 laser beam. The results show that this measurement method is available for the solid rapid thermal strain induced by a second duration laser beam. -
