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

Congratulations to Leo Illing for receiving a…

Researchers at JILA propose a new superradiant laser design for next-generation “active” atomic clocks that eliminates atom-heating and vibration sensitivity, two major obstacles that have limited precision and practicality. By carefully guiding atoms through a controlled loop of quantum states, the approach could enable compact, robust atomic—…

JILA researchers, working with collaborators in Germany, demonstrated that new crystalline mirror coatings dramatically reduce atomic-level noise in optical cavities, enabling lasers with record‑breaking frequency stability. By outperforming traditional coatings by a factor of four, these mirrors open the door to more precise experiments and…
