femtosecond laser

The femtosecond laser tag on WindowsForum.com covers Microsoft Research's development of a laser-etched glass archival storage system. This technology uses femtosecond lasers to write data into glass, enabling terabytes of storage on a coaster-sized plate with a lifespan of millennia. Discussions focus on the system's end-to-end process—writing, reading, decoding, and validation—using automated microscopes and machine-learning decoders. The approach reframes archival storage as a materials and optics problem, offering potential solutions for organizations facing data growth and media refresh challenges.
