Michael Shanahan Dean of Faculty and Professor of Physics<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A century ago, the shortest time interval that could be measured, a millisecond, was available from streak-recording methods, and by 1965 the capabilities of high-frequency electronic circuitry had reduced this limit to a nanosecond. The time-resolution limit dropped precipitously after 1965 due to the invention of the laser and is now less than 1 fs (10<sup>-15<\/sup>s). These ultrafast laser pulses provide a tool for exploring nature in a previously inaccessible time domain; the evolution of nonequilibrium materials can be resolved, chemical reactions can be controlled, phase transitions can be monitored, and energy can be impulsively deposited into materials to create high-energy-density states of matter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Donnelly group carries out experiments to study the interaction of high-intensity laser light with novel microstuctured targets. We develop machines that are capable of producing novel micron and sub-micron sized targets that are developed to study topics such as laser-driven nuclear fusion and the heating mechanisms which allow laser energy to be absorbed on short timescales by solid-density materials. We build, characterize, and do science with our machines at 91̽»¨ Mudd, as well as with our collaborators at the University of Texas at Austin where we have access to some of the most powerful laser systems ever built.<\/p>\n\n\n<div class=\"archive-posts-wrapper page-default wp-block-mudd-latest-posts\">\n\t \n\n  \t<div class=\"archive-heading\">\n\t\t  <h2 class=\"archive-heading-description\">Recent Publications<\/h2>\n\t\t<\/div>\n\t  \t\t            <article class=\"archive-post-wrapper\">\n                          <div class=\"archive-post-summary\">\n                <h3 class=\"h2\"><a href=\"https:\/\/www.hmc.edu\/physics\/research\/publications\/measuring-the-spatial-resolution-of-an-optical-system-in-an-undergraduate-optics-laboratory\/\">Measuring the spatial resolution of an optical system in an undergraduate optics laboratory<\/a><\/h3>\n                          <p>Calvin Leung and Thomas D.
