Lecture
This lecture discusses the breakthrough in digital storage technology using ultrafast laser writing through anisotropic nanostructures in silica glass, leading to the creation of a 5D memory crystal. The storage medium provides high data capacity, thermal stability, and virtually unlimited room temperature life, recognized by the Guinness Book of Records. The lecture explores the potential of challenging traditional cloud storage systems and achieving information immortality. The presentation covers topics such as optical data storage benefits, long-term data preservation, femtosecond lasers, and the mechanism of nanovoid formation. It also delves into the practical applications of femtosecond lasers, including vision-correction surgery and micromachining.
