Paper Abstract

The interaction between Mercury Cadmium Telluride (MCT) and single pulse of Nd:YAG laser with 1.06 micrometers wavelength and 10 ns pulse duration was studied. The impulse delivered to MCT sample was measured by using ballistic pendulum method. The experiment shows that the momentum transfer results from material being ejected from MCT surface under the impinging of intense pulse laser. The impulse coupling coefficient of MCT gets to its maximum 14.3 dyne(DOT)s/J when incident laser power density is about 7.6 X 108 W/cm2. By using 1D model of gas-dynamics, the impulse coupling coefficients have been calculated. The calculated results agree well with measured ones in the region of incident power density larger than 1.5 X 109 W/cm2.
