Experimental studies on coupling coefficient of impulse in materials irradiated by high-energy laser

The coupling coefficient of two kinds of materials (paint A and paint B) irradiated by pulsed high-energy laser was studied experimentally in this paper, and the sensor technique that using the principles of directly measuring the specific time intervals was introduced. Results showed that, under the radiation of high-energy laser, the coupling coefficient of impulse is 4.64×10−5N·W
⁻¹
for paint A, 4.88×10−5N·W
⁻¹
for paint B in the vacuum environment, and the pressure has significant effect on it.
