- Laser Fusion Achieved at NIF
Scientists at the National Ignition Facility (NIF) in Livermore, CA report that for the first time a laser-initiated plasma has produced more energy than was put into it. Although the total amount of energy in the laser pulse was greater than that released, this is considered to be a significant step as greater than unity gain was achieved for the light that actually struck the target. The group published their findings in Nature, the International Weekly Journal of Science. News outlets, including NPR, have reported the story.
- JILA Atomic Clock Hits New Level of Accuracy… and Mainstream Media
A JILA team at Boulder, CO headed by Jun Ye has published their results on a new Strontium-based atomic clock demonstrating accuracy on the order of 1 second for the lifetime of the earth. The clock, as reported in Nature1, has an accuracy of 6.4×10-18 and is based on a lattice of Strontium atoms. The clock surpasses the accuracy of the previous record holders, clocks based on single ions2,3,4.
Though the results were only released as an advanced online publication on 22 January (three days ago at the publication of this post), the clock has already been reported on in the mainstream media, including NPR, Nature World News, and the Daily Mail, demonstrating a widespread interest in atomic physics.
Congratulations to the group for their efforts and results.

- 2013 Nobel Prize in Physics Awarded to François Englert and Peter W. Higgs
The 2013 Nobel Prize in Physics was awarded jointly to François Englert and Peter W. Higgs “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider.”
Congratulations Drs. Englert and Higgs!
- Ana Maria Rey Wins MacArthur Fellowship for Cold Atom Theory Work
JILA Fellow Dr. Ana Maria Rey has been awarded a 2013 MacArthur Fellowship, also known as a “Genius Grant.” Dr. Rey has been developing the theory of cold atom physics including the theoretical underpinnings of ultra-cold optical lattices and the large-scale entanglement between atoms.
We are proud that the MacArthur Foundation has recognized a member of the Atomic, Molecular, and Optical Physics Community for this prestigious award.
Congratulations Dr. Rey!
Each year, the John D. and Catherine T. MacArthur Foundation identifies 20 to 30 exceptionally creative individuals with the potential for important work and provides them with financial support, freeing them to pursue their most innovative ideas. The MacArthur Fellows Program awards unrestricted fellowships to talented individuals who have shown extraordinary originality and dedication in their creative pursuits and a marked capacity for self-direction.

- Vescent Introduces 100 mW DBR laser at 780 nm for Rubidium Spectroscopy
Vescent Photonics is proud to announce the latest in performance improvement to our line of AMO tools. The new D2-100-DBR-780-HP1 Distributed Bragg Reflector diode laser offers over 100 mW of mode hop-free tunable power on resonance with the D2 transitions of Rubidium at 780.24 nm. The new laser also offers improved linewidths of <500 kHz. The HP1 laser can be driven by our D2-105 low-noise current controller and allows for a tight lock to the atomic transitions using the D2-125 Reconfiguration Servo and D2-110 Spectroscopy Module.
The new HP1 still offers all the great advantages of a DBR laser: The integration of the tuning element onto the chip means fast, reliable wavelength control. No PZT and no moving parts result in a stable, robust laser which is much less susceptible to mechanical vibrations than a ECDL. It also means that megahertz feedback and tuning and gigahertz modulation are available. No moving parts allows for a much smaller laser head for deployment in tight spaces.
All the advantages of a DBR and now 100 mW output power and 500 kHz linewidths.
