从理论上和实验上研究了波长为800 nm、持续时间为100 fs的飞秒激光脉冲诱导铜纳米粒子的超快熔化。实验研究了飞秒激光在80 MHz重复频率下烧结铜np分散膜制备的Cu图案。采用具有温度依赖的一维双温度模型，包括动态光学性质和热物理性质的扩展Drude模型，模拟了颗粒的超快熔化和再凝固过程。
The ultrafast melting of copper nanoparticles (NPs) induced by a femtosecond laser pulse with duration of 100 fs and wavelength of 800 nm is investigated theoretically and experimentally. The Cu pattern fabricated from sintering of a Cu NP-dispersed film by the femtosecond laser at a repetition rate of 80 MHz is experimentally studied. A one-dimensional two-temperature model with temperature-dependent material properties, including the extended Drude model for dynamic optical properties and the thermophysical properties, is employed to simulate the particles ultrafast melting and re-solidification process.
