Parallel femtosecond laser processing with a computer-generated hologram displayed on a spatial light modulator (SLM) is demonstrated. Use of the SLM enables performance of an arbitrary and variable patterning in laser processing.

Holographic femtosecond laser processing with multiplexed phase Fresnel lenses for high-speed parallel fabrication of microstructures is proposed. Use of a spatial light modulator (SLM) allows independent tunability of the diffraction peaks, three-dimensional parallelism, and arbitrary, variable features.
The use of the femtosecond laser enables generation of small spot sizes and ablation features. Ablation of the smallfeatures usually requires only a small amount of laser power to be delivered to the ablation spot. When using only a onebeam for the ablation of the small features this process is bound to be time consuming. The spatial light modulator (SLM) together with the computer generated ...

We propose a holographic femtosecond laser processing system capable of parallel, arbitrary, and variable patterning. These features are achieved by introducing a spatial light modulator displaying a hologram into the femtosecond laser processing system. We demonstrate the variable parallel processing of a glass sample.
