stopping_time_mount_union.pdf

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 discussion of the concept of time, we will review...

The role of multiphoton excitation in ultrafast white-light continuum generation, at APS Centennial Meeting 1999 (Atlanta, GA), Thursday, March 25, 1999:
talk_268.pdf
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...

An introduction to femtosecond laser techniques: Part 2, at XIII Escola de Verão Jorge André Swieca de Ótica Quântica e Ótica Não Linear, Instituto de Física de São Carlos (São Carlos, SP, Brazil), Tuesday, January 24, 2012:
talk_1838.pdf
This interactively taught half-day course provides basic knowledge of the measurements of and research with femtosecond laser pulses. Beginning with the basic principles of the interaction of light and matter, we'll discuss the interaction of intense short pulses with matter. Using worksheets we'll address a number of common conceptual misconceptions in an interactive and collaborative setting.
