Web3. apr 2024 · The measured reflectivity has the shape of a double time slit, with a fast rise time and slow decay, given by the convolution of driving pump pulses, probe and material response. Webfecting laser-material interaction is the ma-terial’s ability to absorb laser radiation. this absorptivity is greatly influenced by wave-lengths and temperature [1]. When the laser beam strikes the material, part of the energy is reflected and the rest is absorbed. the absorptivity of some common metals at different laser wavelengths is shown in
