Abstract

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 diffraction peaks are made uniform by changing the center phase and size of each phase Fresnel lens while taking account of the intensity distribution of the irradiated laser pulse and the spatial frequency response of the SLM.
