Paper Abstract

A high-intensity laser pulse can lead to a change of the group index of a material, so that the pulse within that material is slowed to only hundreds of meters per second. This kind of slow-light phenomenon scales with the optical intensity of the pulse. While previous experiments have produced this effect with an elliptical beam passing through a spinning ruby window, a question remains as to whether the effect would be present in a circular beam. Here we use two different methods of producing slow light in a round beam, showing that, while less pronounced than the effect with an elliptical beam, a slow-light effect can be seen in a round beam.
