Ohio State is in the process of revising websites and program materials to accurately reflect compliance with the law. While this work occurs, language referencing protected class status or other activities prohibited by Ohio Senate Bill 1 may still appear in some places. However, all programs and activities are being administered in compliance with federal and state law.

Colorado State University Petawatt-Class Laser is an ultra-short pulse Ti:sapphire laser system that produces ultrahigh-contrast λ = 400 nm femtosecond pulses of up to 10 J, obtained by frequency doubling 800 nm pulses of 30 fs duration.  An intensity of 6.5x1021 W/cm2 is obtained focusing the beam with an f/2 parabola. An f/1 parabola will be available after July 2019 that is expected to deliver intensities >1×1022. The beam/pulse parameters presently offered by the laser are summarized in the Laser Modes table.
