Laser Physics

JILA physicists manipulate light to produce ultrashort laser pulses and coherent light sources at exotic wavelengths. As a leading developer of ultrashort laser pulses, JILA researchers have designed pulsed and single ultrashort pulses of light faster than the speed at which molecules form (1 femtosecond, or 10-15 s) and the speed at which electrons move (1 attosecond, or 10-18 s). JILA researchers pioneered the development of tabletop extreme ultraviolet coherent light sources, which opened a new dimension of laser applications.
 
This research explores the complex dance of electrons in matter, and therefore uncovers answers as to how materials bond and how magnetic systems can be manipulated. These studies have a wide breath of applications, including chemistry, biology, material sciences, medicine, telecommunications, and nanotechnology.

Recent Highlights in Laser Physics

The strange behaviors of high-temperature superconductors—materials that conduct electricity without resistance above the boiling point of liquid nitrogen—and other systems with unusual magnetic properties have fascinated scientists for decades. While researchers have developed mathematical models for these systems, much of the underlying…

Researchers at JILA and the University of Colorado Boulder have developed an innovative platform that combines machine learning with atom interferometry to create a universal quantum sensor. This system uses programmable atom-optic "gates" to reconfigure a single device via software for various precision measurements, such as acceleration,…

Understanding how molecules interact with ions is a cornerstone of chemistry, with applications from pollution detection and cleanup to drug delivery. In a series of new studies led by JILA Fellow and University of Colorado Boulder chemistry professor Mathias Weber, researchers explored how a specific ion receptor called octamethyl calix[4]…
