抄録

<jats:p>The first experiment of time-resolved spectral imaging of liquid in laser ablation is reported. An interferometric spectral imaging system dedicated to the measurements of the laser ablation is constructed. A pair of two-dimensional arrays of images are formed by a lenslet array coupled with a polarization interferometer and superposed on a detection plane. Each image in the array is provided with a varied path difference by the wedge-shaped liquid-crystal polarization interferometer to generate the interference signals. These interference signals include all the information necessary to reconstruct a spectral image and can be collected simultaneously. The mechanism of ablation of phenanthrene/ethanol solution was investigated by making use of the time-resolved spectral images of the laser induced plume. The results suggest that the photothermal processes are dominant in the ablation of the solution.</jats:p>
