High power lasers are increasingly being used as tools to precisely modify materials on length scales as small as one ten-thousandths of an inch. However, our understanding of how ultrashort laser pulses modify materials is handicapped by out-of-date models of laser-induced damage that assume the laser light is monochromatic (i.e. a single color). This proposed project is the first stage of a larger collaborative effort to establish updated models oflaser-induced damage that are compatible with current short-pulsed laser technology. Such a study may greatly improve our ability to predict and control the outcome of many high power laser applications.
