Smoke on the light, fire in the sky.
Most people would love to a holographic display in their rooms, and seriously you might not have to wait too long for this to happen. Japanese researchers demonstrate how lasers can be used to manipulate holograms.
Despite manufacturers have tirelessly designed new types of razor blades for a cleaner shave, the process has stayed virtually unchanged for thousands of years. The difference between a modern razor blade and an ancient roman shaving knife isn’t that large, on a fundamental level at least. This may set to change if the Skarp Laser Razor makes its way into the shaving kit market. The gadget is basically a high-tech razor – named so only by function – that uses a highly focused laser beam instead of a blade.
A 30KW high-power laser was demonstrated by Lockheed Martin after it was used to disable a vehicle more than a mile away. One of the great perks of laser weapons is their phenomenal accuracy. To showcase this, the weapon was directed specifically on the hood of the vehicle, where it fried the engine. The beam from the Advanced Test High Energy Asset, or ATHENA, is believed to be most powerful ever documented in a laser weapon.
Japan just powered up the world’s most powerful laser, a monster that shines a 2-petawatt pulse of light. The pulse lasted only one picosecond, or a trillionth of a second, but during this brief time frame the laser definitely concentrated a phenomenal amount of power.
Astronauts onboard the ISS may soon get a new “toy” – a space laser cannon to blast off space debris that might threaten the space station. Even a tiny scratch or dent could cause massive problems, and with us putting more and more stuff in space, the risk of damage constantly increases too.
Princeton researchers demonstrated a novel type of microwave laser – called a maser – so small that’s the size of a grain of rice. The laser is powered by individual electrons that tunnel through artificial atoms known as quantum dots.
Shells and bullets have evolved significantly in the past couple hundred years since they were first used, but in principle they’ve remained the same – discharge an explosive to propel a projectile. The 21st century might finally make way to a new class of widespread weaponry based on lasers. These are powerful, much more accurate than any explosive projectile and can
The human retina can only detect incident light that falls in waves 400 to 720 nanometers long, so we can’t see microwave or ultraviolet wavelengths. This also applies to infrared lights which has wavelengths longer than visible and shorter than microwaves, thus being invisible to the human eye. Apparently, this isn’t entirely true. In some special conditions, the human eye can indeed detect
High speed photography is no longer a new thing… but then again, it depends what you mean by high speed photography; you likely don’t mean one hundred billion frames per second (100,000,000,000 fps) – but that’s exactly what Liang Gao, Assistant Professor at Stony Brook University means. He and his team have developed the world’s fastest receive-only 2-D camera. Using the
For the first time, researchers at the University of Basel used an ultracool atomic gas to cool a very thin membrane to less than one degree Kelvin. The new technique might enable novel investigations of quantum mechanics phenomena and precision measuring devices. Coldest matter in the world lends its freeze In the ultracold world, produced by methods of laser cooling
