The numerical simulations were used to predict the profile of analogous microstructures following excimer laser ablation to obtain desired micro-optical components. The simulation technique applied in the excimer laser ablation can reduce the quantity of machining experiments. The ablated microstructures with surface roughness of Ra < 20 nm were successfully machined into micro-optical components for further applications. The excimer laser machining parameters included laser energy, shot number, and repetition rate. 3-D microstructures formations were numerically simulated. Various micro-optical components with low aspect ratios can utilize these laser ablation numerical simulations and to form desired application geometries.
