<p>The paper presents the response of an infinite fibre-reinforced photo-thermoelastic plate of width 2<i>d</i>, loaded with non-viscous fluid layers of widths <i>h</i>₁ and <i>h</i>₂ on the upper and lower sides, respectively. An internal heat source of constant magnitude and a focused laser beam (photothermal excitation) are acting in the plate. The photo-thermoelastic effect considers the plasma-generated electron density field coupled with the thermoelastic waves. The analytical expressions of displacement, stresses, temperature field, and carrier density (plasma waves) are obtained by normal mode analysis technique. The numerical values of the expressions are evaluated using MATLAB. The graphical results are presented to show the effect of different photo-thermoelastic theories with and without reinforcement and with varying plasma-thermal coupling parameters.</p>
