In this work, a new, to the best of our knowledge, model of effective lift-off threshold of an oxide/metal target is presented. The influence of nonlinear processes in the oxide layer on its removal from the metallic samples using a picosecond laser was investigated. Nonlinear and saturable absorption in the layer was incorporated into modeling for prediction of effective laser lift-off threshold fluence change with varying peak intensities in a -scan-type experiment for the first time. The new model coincides well with the experimental results.
在本工作中，据我们所知，提出了一种新的氧化物/金属靶材有效剥离阈值模型。研究了氧化物层中的非线性过程对使用皮秒激光从金属样品上移除该层的影响。首次将该层中的非线性和饱和吸收纳入模型，以预测在 -扫描型实验中，随着峰值强度变化，有效激光剥离阈值通量的变化。新模型与实验结果吻合良好。
