A standard 5-Mv green laser pen may be cheap to buy, but it can't really do anything. The intensity of the light that it puts out is minuscule in comparison to that of an expensive laser pointer, and…

Many industrial and commercial products require intricately designed parts that would be impossible to make via normal lathing and machining. Laser cutters can make very precise cuts without warping…

Lasers are being used increasingly as machine tools. The heat from its intense light can cut many materials. The light is precisely guided by a computerized machine, making the laser cutter adaptable…

The PS3 video game console relies on a laser inside of the Blu-ray drive in order to play games and watch movies. A defective laser renders the PS3 basically useless and is an expensive repair that…

The PlayStation 3, by most standards, is a reliable console. Like any other piece of electronic equipment, however, the PlayStation 3 will eventually have problems. One issue that may arise is the…

Although cleaning the disc-reading laser eye on a CD or DVD player is as simple as playing a special CD or breaking out the Windex and lint-free cloth, cleaning the laser eye on a PlayStation 2 is not…

In "Spiderman 3", you must face off against two lizard bosses, each of which requires a different strategy to defeat. The second boss, known as Mega-Lizard, may seem hard at first, but when you know…

Laser eye surgery refers to a handful of refractive eye surgeries that use powerful lasers to alter the shape of the cornea. The goal of refractive eye surgery (be it laser-assisted or otherwise) is…

Radiation--which is invisible to the human senses--was discovered in the late 19th century. Scientists and researchers needed to investigate this phenomenon, which led to the invention of devices that…

A do-it-yourself laser engraver for wood crafts or pictures drawn on wood can achieve incredible results. Wood laser engravers typically have a high level of accuracy when compared to burning, and…

Lasers have allowed engravers to add more details than ever to their artwork. The result is higher quality engravings on a wider range of materials that adorn business entryways, homes and holiday…

Developed in the early 1960s, the laser has proved to be indispensable in many areas of research, engineering and commerce. Many kinds of lasers have been developed since then, spanning a power range…

The CO2 gas laser is one of the oldest and most common types of lasers in the world. The first CO2 laser was built by Kumar Patel in 1964, at Bell Labs in New Jersey. CO2 lasers are used today in many…

Laser is an acronym for light amplification via the stimulated emission of radiation. More colloquially, it is a light that produces an intense beam of light. A maser is a laser that uses…

A laser beam is a narrow, coherent light beam created by a process called "stimulated emission." "Laser" is actually an acronym which stands for Light Amplification by Stimulated Emission of…

Laser boresighters are helpful tools to calibrate a scope for a firearm. Many of the models of laser boresighters are universal, meaning that with the proper adapter, the boresighter can accommodate…

It is relatively easy to recreate those classic blaster noises from "Star Wars," and they are sure to bring lots of fun! Just follow these steps and you'll be reenacting "The Emperor Strikes Back" in…

LASER, meaning light amplification by stimulated emission of radiation, first appeared in a scientific paper in 1958. With that publication, the laser became a new form of high technology used for…

With the ncreasing amount of accessories available for firearms today, a universal option to attach those accessories becomes necessary. The Weaver Mount, also called the Weaver Rail, is one such…

A laser tachometer can be used to measure the number of rotations per minute (rpm) of a spinning shaft or a disk. Laser tachometers have the advantage of being able to measure rpm without being…

Laser engraving is the application of marks or designs to an object through the use of a powerful laser. Although simple in concept, the process of laser engraving is quite complex. A laser engraving…

Semiconductor lasers are solid-state tools that are composed of dual outside semiconductor layers that are separated by a central layer. Semiconductor layers produce laser radiation when charged…

Laser wood engraving is extremely detailed and intricate art burned into wood using lasers. Laser wood engraving is a specialized type of woodburning that results in beautiful pictures with a great…

Laser etching, also known as laser engraving, is the process of using concentrated, amplified beams of light to mark one or more objects. The laser is often controlled by a computer system as the…

The term laser stands for "Light Amplification by Stimulated Emission of Radiation." A laser is a device that emits an amplified, coherent beam of electromagnetic radiation usually within the…

A semiconductor can be made by adding a small amount of impurity when forming a silicon matrix. This is called doping. Different impurities create a matrix which is either positive or negative.…

Laser etching is done with a laser engraving or cutting machine. It is a very simple process to learn and can be done on a variety of materials. Some examples of possible materials include wood,…

The aid of a laser pointing device on a pistol or rifle allows much greater accuracy and precision in striking the target. Once these types of devices were only available to law enforcement agencies,…
