Have you ever tried writing with a beam of light? Sounds impossible, doesn't it, but it's exactly what a laser printer does when it makes a permanent copy of data (information) from your computer on a piece of paper. Thanks to sci-fi and spy movies, we tend to think of lasers as...
Derived from the terms "excited" and "dimers," these types of lasers use reactive gases, such as chlorine and fluorine, mixed with inert gases such as argon, krypton or xenon. When electrically stimulated, a pseudo molecule (dimer) is produced. When lased, the dimer produces light in the...

Photo: Lenses in the headlamps of this car focus beams of light down onto the road so you can see where you're going. Some car headlights use Fresnel lenses to make powerful beams, just like lighthouses! Our eyes contain probably the most amazing lenses of all. Think what happens when...
(dvds), and blu-ray discs. these discs use lasers to read and write data by altering the physical properties of the disc's surface, allowing for non-volatile and portable storage of large amounts of data. what is optical character recognition (ocr)? ocr is a technology that enables the ...

Laser printers are popular for businesses and for those who need to print out a high volume of documents. These printers use lasers and electromagnetism to create documents, and they’re generally much faster than inkjet printers. Most laser printers can’t print color documents, but we do prod...
stimulated emission of radiation (laser) mouse are two different types of computer mice that use distinct technologies to track movement. Optical mice use light emitting diodes (LEDs) for tracking and work well on non-glossy surfaces. Laser mice use lasers, offering better performance on various ...
Doctors use lasers for hyperpigmentation as part of an outpatient procedure. Each session lasts between 30 minutes and one hour, and it may take more than one session with the laser for hyperpigmentation to disappear. The laser works by evaporating the damaged area, revealing the layer of skin ...
How Do Robot Vacuum Navigate Robot vacuums use different technology and sensors to navigate your home. Generally, smart vacuums start by mapping the environment – utilizing cameras, lasers, or infrared sensors to create a detailed map. After scanning the surroundings to detect walls, furniture and...
