Abstract Background: Laser therapy offers precise medical treatment by directing focused light beams to specific areas without harming surrounding tissue. This precision is particularly valuable in tissue treatment, including cancer therapy, where minimizing collateral damage is critical. The current study focuses on bio-thermal dynamics and thermal damage in biological tissues induced by multiple pulse-laser irradiations. Model: To examine the thermal behavior, the Local Thermal Non-Equilibrium (LTNE) bioheat Transfer model with porosity and dual lag effects is developed. The model contains partial differential equations and is solved by numerical method. Results: Obtained results demonstrate temperature variations and thermal damage in tissues, influenced by factors like laser intensity, incident duration, and tissue porosity. Higher intensity of laser and longer laser durations increase the temperature distribution and thermal damage as well. Porosity inversely affects temperature distribution, with higher porosity leading to decreased distribution. Novelty: This study introduces the application of multi-time lasers, a novel approach that has not been previously explored in the literature. By investigating the impact of laser parameters and tissue characteristics, it enhances understanding and guides the development of effective laser therapies for medical applications.
