Since I sort of implied a series in the previous post, and I have no better ideas, here’s a look at Thursday’s DAMOP program:

Anatomy of a Conference: DAMOP Day 1
The conference I’m at this week is the annual meeting of the Division of Atomic, Molecular, and Optical Physics of the American Physical Society (which this year is joint with the Canadian version, the Division of Atomic and Molecular Physics and Photon Interactions, or “DAMPΦ.” The Greek letter is a recent addition– as recently as […]
The Past and Future of the Laser
While it’s not aprt of the official LaserFest package of stuff, Physics World is marking the 50th anniversary of the laser with a couple of really nice pieces on lasers in science and popular culture: Where next for the laser interviews six laser experts– Claire Max of UCSC, Bill Phillips of NIST, Steven Block of […]
The Most Amazing Laser Application of All Time Is…
Voting has closed on the Laser Smackdown poll, with 772 people recording their opinion on the most amazing of the many things that have been done with lasers in the fifty years since the invention of the first working laser (see the Laserfest web site for more on the history and applications of lasers). The […]
Last Call for Laser Smackdown Voting
With over 700 votes cast in the Laser Smackdown poll in honor of the 50th anniversary of the laser, laser cooling has opened a commanding 20-vote lead in the race to be the Most Amazing Laser Application of All Time. If you prefer one of the other options, you have only six hours left to […]
Laser Smackdown: Final Days of Voting for the Most Amazing Laser Application
We’re just over 600 votes in the Laser Smackdown poll in honor of the 50th anniversary of the laser, as of early Friday morning. I notice that it has moved off the front page of the blog, though, so here’s another signal-boosting repost, just so we have as many votes as possible, to establish maximum […]
Reminder: Vote for the Most Amazing Laser Application of All Time
As of 1:45 Monday, 217 people have cast votes in the Laser Smackdown poll. That’s not bad, but it’s currently being handily beaten by the 271 people who have voted for a favorite system of units. The nice thing about using actual poll services for this sort of thing, though, is that I can re-post […]
Laser Smackdown: Vote for the Most Amazing Laser Application
In 1960, the first working laser was demonstrated, and promptly dubbed “a solution looking for a problem.” In the ensuing fifty years, lasers have found lots of problems to solve, but there has been no consensus about which of the many amazing applications of lasers is the most amazing. Now, in 2010, as we celebrate […]
Amazing Laser Application 12: Laser Guide Stars!
What’s the application? Producing artificial “stars” to serve as a reference for telescopes using adaptive optics to correct for atmospheric turbulence. This allows ground-based telescopes to produce images that are as good as those from the Hubble Space Telescope. What problem(s) is it the solution to? “How can I make this giant telescope produce even […]
Amazing Laser Application 11: Frequency Combs!
What’s the application? An optical frequency comb is a short-duration pulsed laser whose output can be viewed as a regularly spaced series of different frequencies. If the pulses are short enough, this can span the entire visible spectrum, giving a “comb” of colored lines on a traditional spectrometer. This can be used for a wide […]
