The laser’s 51st birthday

Since this date was made so much of in 2010, I feel compelled to point out that today is the 51st anniversary of Ted Maiman‘s first working laser. In honor of the date, I’m wearing my “Lasers Rock!” T-shirt from last year’s CLEO concert. After all, think of the billions of rock songs that laser-powered devices have played over the past quarter-century. Lasers really DO rock!

An optical scientist to watch: Jun Ye

I’ve heard of Jun Ye before, mainly through writing and editing articles about optical frequency combs, super-accurate atomic clocks and related topics. Today I got word that Ye, a fellow of NIST and JILA, has been elected to the U.S. National Academy of Sciences, a high honor indeed.

Ye studied for his Ph.D. under John (“Jan”) Hall, one of the Nobel Prize winners I was lucky enough to meet while I worked for OSA – The Optical Society. As folks like Ted Hänsch and Steven Chu can attest, studying under, or working closely with, a Nobel laureate is a great foundation for a scientific career. Keep an eye on Ye for more interesting research.

Arthur Schawlow’s 90th

Today Arthur L. Schawlow would have turned 90 years old. Now, I don’t go around memorizing the birth dates of Nobel physics laureates as a matter of course, but Schawlow has been on my mind quite a bit these last few months, because I wrote a biographical article about him, and it’s the cover story of this month’s issue of Optics & Photonics News. It’s actually the “open content” offering for this month, so everyone can read it, not just OSA members. 🙂

Why did I want to write about Schawlow? I confess that before I joined the OSA staff in 2005, I had never heard of the gentleman. But one of my first tasks was to compile a list of interesting things that had happened in 1975, the year that OPN’s predecessor publication, Optics News, was founded. So I looked up the name of that year’s president of OSA, and it turned out to be Schawlow, so I asked our creative director whether she had any interesting photos of him in the files. She found several, and one in particular — of a grinning Schawlow poised to administer a Ping-Pong paddle spanking to another OSA official from the 1970s — made me roar with laughter. Since I had also noticed by then that Schawlow was a Nobel laureate for something or other, I suggested (after wiping the tears away) that we might want to pick something a little more dignified for the page of 1975-era trivia I was assembling. We ended up republishing the famous snapshot of Schawlow with his “laser ray gun” and double balloon, which now graces the cover of the magazine.

Over the years, I got more curious about Arthur Schawlow. I cross-checked the list of Nobel laureates and past OSA presidents and found that his name was the only one on both lists. I learned that he and Charles Townes co-wrote one of the most important papers in laser history back in 1958, but Townes was still around to enjoy LaserFest and Schawlow — his brother-in-law, even — was not.

So I pitched the idea for a feature story on Schawlow to my editor, and I got the assignment to write it for this round-number anniversary of his birth. I hope I struck a good balance between enumerating his scientific achievements and capturing the personality that made him so memorable to OSA members of an earlier generation.

CLEO is starting!

Just a reminder: For the next few days I’ll be blogging about CLEO, the big laser conference in Baltimore (Maryland, U.S.A.), for the Optics & Photonics News (OPN) blog. Also, I’ll try to tweet as often as I can from the OPN Twitter account, @OPNmagazine.

If all my efforts don’t fill your need for CLEO news, then check out the CLEO social media hub for all the latest blogging, tweeting, and Facebook/LinkedIn goodness.
