Abstract：

Experimental results show that final deformation direction of the specimen depends on the composition peculiarity of material, away from the laser beam or towards the laser beam through measuring the dynamic micro-deformation of the specimen under the condition of non-melting by the means of laser beam reflex amplifier system. The conclusion perfects the mechanism of laser bending and lays a foundation of research on the process of laser bending further.
