Complete numerical simulations are given under SciLab® and MATLAB® coding environments, concerning propagative acoustic wavefronts, for laser picosecond ultrasonics under multiwavelength conditions. Simulations of the deformation field and its propagation into bulk material are given under different wavelength configurations for optical pump and probe beams, which are used to generate and to detect the acoustic signal. Complete insights concerning the dynamics of the acoustic waves are given, considering the absence of carrier diffusions into the material. Several numerical approaches are proposed concerning both the functions introduced to simulate the wavefront (Heaviside or error) and the coding approach (linear/vectorized/Oriented Object Programming), under the pure thermo-elastic approach.

在SciLab®和MATLAB®编码环境下，针对传播波长的波前，针对多波长条件下的激光皮秒超声波，提供了完整的数值模拟。在不同的波长配置下，对用于泵浦和探测光束的形变场及其在块状材料中的传播进行了仿真，这些光束用于生成和检测声信号。考虑到没有载流子扩散到材料中，给出了关于声波动力学的完整见解。几个数值方法提出了关于两个引入到模拟波前（功能海维赛德或错误）和编码方法（线性/量化/纯粹的热弹性方法下的定向对象编程）。
