Abstract: Theoretical and experimental studies of thermal self-defocusing and self-focusing CW laser beams in liquids and solids are given. An analytical theory of thermal self-actions, including ...

The electrons in the beam interact with the electrons bound to the metal atoms to create X-rays," he said. "At NIF, we use the high-power laser beam instead of an electron beam to make the X-rays ...

Most theoretical studies on "beam riders" for interstellar travel have focused on laser beams, which are composed of particles of light called photons. Notable examples include laser-powered ...

Most laser cleaning setups use scanning optics. These move the beam at multiple meters per second to project a desired shape, such as a circle or rectangle, onto the surface. But what is laser ...

The black and white picture shows a bright laser beam being fired from the Preble during a demonstration at sea to verify and validate the "functionality, performance, and capability" of the ...

The HP LaserJet M209d is a sterling value among low-cost, print-only mono laser printers. (If you're considering an inkjet but print only occasionally, it's a tempting alternative.) Its paper ...

Hard Kill which directly destroys a target using high-intensity laser beams, and Soft Kill which disrupts electronic components of enemy systems, effectively blinding or disabling them. The weapon ...

If shaving is growing tiresome, consider laser hair removal: This method damages hair follicles to reduce growth over time, ultimately giving more long-term results than using a razor. After ...

For precision, speed, and fine-detail, only the best laser engraver will make the cut. I tested out a range of laser engraving machines, and these are my top-rated recommendations for crafters ...

The best laser printer is often the top choice for office and home office use. Excelling at document printing, laser printers have a reputation for producing crisp text, fast print speeds ...
