Abstract: In this paper, the improved modified extended tanh function method (IMETFM) is introduced for analyzing the influence of laser pulse on a thermo-elastic with temperature-dependence under a dual phase lag model (DPL). Nonlinear thermo-elasticity examines cases in which a material’s response to changing thermal loads causes considerable changes in both its geometry and material properties. This field is crucial for effectively describing real-world phenomena, such as thermal stresses in large-scale structures, the behavior of materials at high temperatures, and the intricate interactions between mechanical and thermal fields. The proposed method generated a variety of exact solutions featuring distinct free parameters, including hyperbolic, rational, bright solitons , singular solitons , dark solitons , exponential, polynomial, and Jacobi elliptic solutions. Additionally, some of the results for displacement component, temperature, and stress tensor are presented through graphical illustrations.
