本研究的目的是分析材料的热影响区，如肉样品，araldite树脂模拟组织模型，和纤维复合材料照射使用锁模短脉冲激光器的脉冲宽度为200 ps。的径向表面温度分布进行了比较，与连续波（CW）激光的平均功率相同。短脉冲激光导致比具有相应高峰温度的连续激光更局部化的加热。一个参数的研究，解决脉冲串频率，材料厚度，和量的散射体和吸收剂在介质中和不同的初始样品温度的影响进行，和测得的温度分布进行比较与理论非傅立叶双曲线公式和傅立叶抛物线热传导公式为连续波和脉冲激光的情况下。
The purpose of this study is to analyze the heat-affected zone in materials such as meat samples, araldite resin-simulating tissue phantoms, and fiber composites irradiated using a mode-locked short pulse laser with a pulse width of 200 ps. The radial surface temperature profiles are compared with that of a continuous wave (CW) laser of the same average power. The short pulse laser results in a more localized heating than a continuous laser with a corresponding high peak temperature. A parametric study addressing the effect of pulse train frequency, material thickness, and amount of scatterers and absorbing agent in the medium and different initial sample temperatures is performed, and the measured temperature profiles are compared with the theoretical non-Fourier hyperbolic formulations and Fourier parabolic heat conduction formulations for both CW and pulsed laser cases.
