The Economist has a great piece about researchers at the Chinese Academy of Sciences have developed a digital cinema projector that uses lasers as the main display technology. In doing so, these projectors are able to display a staggering 80 percent of th...

Already gaining ground in the U.S. as a diagnostic tool to measure the shape and condition of underground pipes, laser profilers are beginning to find favour with Canadian contractors. Laser profilers cast a circular beam of laser light around the per...

Minuscule traces of cells can be detected in a mineral likely present on Mars, a new study shows. The results, obtained using a technique developed at the U.S. Department of Energy's Idaho National Laboratory, could help mission scientists choose Martian ...

For classic rock fans of a certain vintage, it's a rite of passage up there with attending your first concert, or sneaking your first beer. And for others, it might be as close as they will get to seeing an old-fashioned 1970s arena rock spectacle. We'...

In the past two and a half thousand years, the temples of the Acropolis have suffered fire, bombing and earthquake. Now, scientists are trying to save them from a new modern enemy: pollution. Standing on a hilltop at the centre of Athens, a city of 4 m...

The U.S. Air Force has awarded Boeing a new contract worth up to $30 million for the next phase of development on the Advanced Tactical Laser. The ATL is a C-130H aircraft outfitted with a 12,000-pound high-energy chemical laser module that would be ...

Northrop Grumman Corporation has delivered a compact, standalone, 15kW high-power, solid-state laser developed for the U.S. Air Force Research Laboratory (AFRL) at Kirtland Air Force Base, N.M. Called Vesta II, the laser was a sole source add-on to the ...

The Boeing Company industry teammates and the U.S. Missile Defense Agency on Sept. 7 achieved a major milestone in the development of the Airborne Laser (ABL) missile defense program. The firing a high-energy chemical laser onboard the ABL aircraft for th...

HUNDREDS, possibly thousands, of women are suffering permanent skin damage at the hands of untrained beauty therapists who are operating laser and intense pulsed light machines. In the worst cases, therapists are misdiagnosing melanomas as pigmentation a...

DNA, the molecule that acts as the carrier of genetic information in all forms of life, is highly resistant against alteration by ultraviolet laser, but understanding the mechanism for its photostability presents some puzzling problems. A key aspect is th...

A Texas jury has found that Palomar’s products do not infringe on a Candela patent. Candela had accused eight Palomar handpieces of infringing on three Candela Patents. Curiously, just days before the start of trial, Candela dropped its accusations a...

The UK is to take a co-ordinating role in a new project that was launched this week that will promote the use of lasers with nuclear fusion as a future energy source, writes Rachel Johnson. Funded by the European Commission and the UK, French and Czech...

Sony Corp developed a 635nm red semiconductor laser with an optical output of 7.2W, which the company claims is "the world's highest output" in this wavelength range. The red semiconductor laser prototypeThe laser is intended for use as a light source...

The military may one day manage to get a modified 747 to blast missiles out of the sky, with a real-life energy cannon. But even if the so-called "Airborne Laser," or ABL, functions as promised, it still won't be all that useful, nay-sayers contend. With ...

In a wavelength-tunable laser, some kind of adjustable optical bandpass filter such as a birefringent tuner is often used for adjusting the emission wavelength. As such a tuner introduces wavelength-dependent power losses, one may wonder to which extent i...
