Keeping a tight focus on matter — •Philip St. J. Russell — Max-Planck Institute for the Science of Light, Guenther-Scharowsky Strasse 1/24, 91058 Erlangen, Germany

Photonic crystal fibres uniquely permit laser light to be kept tightly focused in a hollow micron-sized channel over propagation lengths of hundreds of metres. Recent experiments show how this can be used to enhance nonlinear light-matter interactions in gases and to trap and propel small particles using light.
