Graduate Student Matt Norcia (Thompson group) received a JILA Scientific Achievement Award on February 18. The announcement took place during a special snack time in the Sunrise Room of the JILA Tower.

Norcia was cited for building a strontium cavity-QED experiment from scratch. Norcia’s advisor, James Thompson, nominated him for the prestigious award. Thompson noted that Norcia’s...

When the Thompson group first demonstrated its innovative “superradiant” laser the team noticed that sometimes the amount of light emitted by the laser would fluctuate up and down.  The researchers wondered what was causing these fluctuations. They were especially concerned that whatever it was could also be a problem in future lasers based on the same principles.

In the group’s...

The Thompson group, with theory help from the Holland group, recently demonstrated a superradiant laser that escapes the “echo chamber” problem that limits the best lasers. To understand this problem, imagine an opera singer practicing in an echo chamber. The singer hears his own voice echo from the walls of the room. He constantly adjusts his pitch to match that of his echo from some time...

To be the best they can be, optical atomic clocks need better clock lasers — lasers that remain phase coherent a hundred times longer than the very best conventional lasers. For instance, light from the clock laser in Fellow Jun Ye’s lab can travel around the Earth 10 times before it loses coherence. However, realizing the potential of the lab’s optical clock requires that the laser light...

Precision laser science at JILA has taken a quantum leap, thanks to some seminal theory work by the Murray Holland group and promising basic research and technical development by the James Thompson and Jun Ye groups. The story began in 2004 just after Ye had finished a talk on the advantages of focusing on strontium (Sr) in basic physics research. Daniel Kleppner, Lester Wolfe Professor of...
