A new type of diode laser, called the quantum cascade laser (QCL), may eventually change this situation. Diode lasers are inherently compact and suitable for mass-production, which has led to their widespread and low-cost use in everyday products, including CD and DVD players.
Funding decisions for the first round of the Excellence Initiative have been made.
After a total of 88 proposals for the three funding lines were evaluated and discussed by international review panels and the Joint Co...
A compact, inexpensive method for stabilizing lasers that uses a new design to reduce sensitivity to vibration and gravity 100 times better than similar approaches has been demonstrated by scientists at JILA.
Just as clouds block the sun, they interfere with laser communications systems, but Penn State researchers are using a combination of computational methods to find the silver lining and punch through the clouds.
By combining two techniques, magnetic resonance imaging (MRI) and near-infrared optics, researchers at Dartmouth College and Dartmouth Medical School may have devised a new, potentially more accurate method for diagnosin...
Researchers have created a new laser-silicon hybrid computer chip that can produce laser beams that will make it possible to use laser light rather than wires to send data between chips, removing the most significant bottleneck in computer design.
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS).
But today's best atomic clocks are so accurate—neith...
ASU scientists Rudy Diaz and Stuart Lindsay will lead a research group on a three-year, $1.1 million grant from the National Science Foundation for an innovative project designed to break through the current technological hurdles of solar energy.
An international team including researcher Ermanno Borra, from Université Laval's Center for Optics, Photonics, and Laser, has taken another step toward building a liquid telescope on the moon.
The resear...
The primary goal of this conference is to bring together scientists, engineers, and clinicians interested in the application of optics to biotechnology, medicine, and surgery.
In addition to formal presentations, this...
Astronomers have used powerful adaptive optics technology at the W. M. Keck Observatory in Hawaii to reveal the precise locations and environments of a pair of supermassive black holes at the center of an ongoing collisi...
Astronomers have discovered the exact location and makeup of a pair of supermassive black holes at the center of a collision of two galaxies more than 300 million light years away.
Using adaptive optics (AO), which c...
