  • Spatially chirped pulses for femtosecond laser ablation through transparent materials
    Patent number: 9545689
    Abstract: Temporal focusing of spatially chirped femtosecond laser pulses overcomes previous limitations for ablating high aspect ratio features with low numerical aperture (NA) beams. Simultaneous spatial and temporal focusing reduces nonlinear interactions, such as self-focusing, prior to the focal plane so that deep (˜1 mm) features with parallel sidewalls are ablated at high material removal rates.
    Type: Grant
    Filed: December 9, 2013
    Date of Patent: January 17, 2017
    Assignee: Colorado School of Mines
    Inventors: Jeffrey Squier, Dawn Vitek, Charles Durfee, Daniel Adams, David Kleinfeld
