Lasers are useful because they produce powerful beams of collimated, coherent light. The fact that laser light is monochromatic (narrowband spectral output) is an advantage much of the time ...

Earlier this year the U.S. Army shot down a number of hostile drones in the Middle East using a weapon long dismissed as more science fiction than reality—the laser. After decades of costly ...

The development of laser weapon systems offers a potential solution, providing a cost-effective and continuous defense option. -Despite promising advancements, challenges such as power ...

One solution could come from a technology called “free-space optics” (FSO), which uses lasers to transfer data through the air. It was pioneered in the 1960s by NASA and for decades has been a ...

If you need high-quality printing in a snap, a laser printer can produce clean, sharp prints in as little as a few seconds. But, after three weeks of testing each device, not all laser printers ...

Those tests in the 1980s led to the US government building the National Ignition Facility (NIF) in California, a project to see if nuclear fuel pellets could be ignited using a powerful laser.

Lasers are a common tool in dentistry. They can be used for teeth whitening, tooth decay, gum disease, and mouth lesions. Using lasers in dentistry for tooth tissue procedures and other dental ...

Few treatments can compete with lasers for targeting fine lines, wrinkles, and other skin texture concerns. Fractional lasers (often called Fraxel, the most widely known brand of these treatments ...

Although laser communication in space is far from novel, its wide-scale deployment as seen with SpaceX’s Starlink satellite internet constellation has brought the technology to the forefront ...

When the first laser and inkjet printers for PCs arrived—in the mid-1980s—each could print only in monochrome, and their respective advantages were obvious. The differences are more nuanced ...

The best color laser printers are a great investment that can save you time and money compared to cartridge-based inkjet printers. Laser printers use toner, which lasts a long time, delivering a ...
