Abstract

Gas-filled hollow core fibers are a promising and unique platform for generation of ultrafast and wavelength tunable UV light. We present recent advances from our lab focused towards two vastly different industrial applications: Laser processing of solar cells and scatterometry. For processing of solar cells, we use the intrinsic wavelength tuning ability to investigate the potential for selective ablation and wire bonding. For scatterometry, which requires a broadband, flat, and low noise spectrum, we use pump modulation to create a pseudo-supercontinuum.
