    The role of multiphoton excitation in ultrafast white-light continuum generation, at APS Centennial Meeting 1999 (Atlanta, GA), Thursday, March 25, 1999:
    When a powerful ultrashort laser pulse is focused into a transparent medium, it can undergo severe spectral broadening and be transformed into a white-light spectral continuum. Despite the continuum's widespread use as a tunable ultrafast light source, the mechanisms of continuum generation are still poorly understood. We report an experimental investigation of white-light continuum generation in transparent media using 100-fs pulses from a Ti:sapphire laser system. We measured the continuum's spectral width for a variety of materials and pump wavelengths. The materials were selected to cover...

    Stopping Time, at 2000-2001 Lowell First Friday Lectures, Museum of Science (Boston, MA), Friday, October 6, 2000:
    Time is of philosophical interest as well as the subject of mathematical and scientific research. Even though it is a concept familiar to most, the passage of time remains one of the greatest enigmas of the universe. The philosopher Augustine once said: "What then is time? If no one asks me, I know what it is. If I wish to explain it to him who asks me, I do not know." The concept time indeed cannot be explained in simple terms. Emotions, life, and death - all are related to our interpretation of the irreversible flow of time. After a short introduction to the concept of time, Dr. Mazur... Read more about Stopping Time
    Stopping Time, at Public Lecture, University of Puerto Rico, Rio Piedras (San Juan, PR), Tuesday, March 6, 2001:
    Time is of philosophical interest and is also the subject of mathematical and scientific research. Even though it is one of the most familiar concepts, the passage of time remains one of the greatest enigmas of the universe. The Platonist Augustine has said: 'What then is time? If no one asks me, I know what it is. If I wish to explain it to him who who asks me, I do not know.' The concept time can indeed not be explained in simple terms. Emotions, life and death all are related to our interpretation of the irreversible flow of time. The more we think about it, however, the more unclear the... Read more about Stopping Time
