This study is concerned with the thermo-mechanical interactions of ultra-short laser pulse as input heat source with homogeneous isotropic microstretch-thermoelastic solid half-space with microtemperatures. The medium is subjected to normal force and thermal source. Integral transform (Laplace transform and Fourier transform) technique has been applied to the basic equations to solve the problem. Expressions have been obtained for normal stress, tangential stress, microstress and temperature distribution in the transferred domain. The numerically computed results are shown graphically. Some special cases are also deduced from the present investigation.
