A New Method for Detecting Jet Impact Force of Laser Cavity

Abstract:

Based on the deflection effect resulted from deformation, a new experiment device for measuring the jet impact force of laser cavity is developed. The device has been used in experiment and the typical signal of jet impact force was obtained. The variational characteristic of the force with time was given. The result shows that during the experiment the target material sustains three forces. In order of time, the first force is the laser ablation force, and the other two forces are jet impact forces. The first jet impact force is greater than the ablation force and the second jet impact force is smaller than the first jet impact force.
