Computers at Work on Ultrafast Laser Design
Catalin V. Filip
Ultrafast lasers have evolved so quickly in the last decade that engineers have only recently incorporated computer technology into their design. Today, new computer programs could provide increased precision and performance for... more>>
Advances in Yb:Fiber Frequency Comb Technology
Femtosecond-laser frequency combs revolutionized the field of precision metrology after their introduction in 1999. Today, they are commonly used in atomic clock calibration, low-noise frequency synthesis, astronomical spectrograph calibration and precision spectroscopy. Scientists are now pushing to extend frequency combs into the mid-infrared and extreme ultraviolet spectral region with Yb:fiber technology. more>>
Light, Atoms and Nuclei: The Optical Discovery of Deuterium
Charles W. Clark and Joseph Reader
Eighty years have passed since atomic spectroscopy was used to discover deuterium, or “heavy hydrogen.” The element has played a transformational role in the development of nuclear energy and isotope chemistry. Currently, it is helping astronomers to understand the very origins of our universe. more>>
Remembering the Million-Hour Laser
On the 50th anniversary of the diode laser, Richard Dixon reminisces about the program that took the device from laboratory curiosity to the applied technology that forms the backbone for terrestrial and undersea communications. more>>
Team Builds Mid-infrared Lumped Nanocircuit
Researchers at the University of Pennsylvania (U.S.A.) have built a working 2-D optical nanocircuit designed out of “lumped” elements analogous to the familiar building blocks of electronic circuitry. more>>
What Makes a Good Website for Scientists?
Marc J. Kuchner
More and more scientists are creating their own websites to showcase their careers and interests. What constitutes a successful site to our peers? The answer might surprise you.
An Optics Road Trip in Rural Australia
Björn Sturmberg and Owen Brasier
Two members of the University of Sydney OSA student chapter report back from their two-week road trip through a remote area of the Australian Outback, during which they gave high school students a unique introduction to hot topics in optics.
The History of OSA
Edward O. Hulburt: Frederick Ives Medalist, 1955
John N. Howard
Edward O. Hulburt, recipient of the 1955 Frederick Ives Medal, was a pioneer in atmospheric research. He is best known for his rocket experiments that examined ultraviolet and X-radiation in the ionosphere and for establishing optics research at the Naval Research Laboratory in Washington, D.C., U.S.A. more>>
