Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.
Anthony, born on August 20, 1992, [1] grew up in Goodfield, Illinois.Anthony began experimenting with lasers at the age of 12 after learning about them in school. After working for a summer to save for a video camera, he began to record his pyrotechnic experiments with his close friend Josh, and he began posting his experiments on YouTube in 2006.
Combining a pico projector with a webcam, a laser pointer, and image processing software enables full control of any computing system via the laser pointer. Pointer on/off actions, motion patterns (e.g., dwell, repetitive visit, circles, etc.) and more can all be mapped to events which generate standard mouse or keyboard events, or user ...
The Hercules 500, made by Laserglow, held the world record for the world's most powerful handheld laser in 2012, [9] and appeared in the Guinness Book of World Records in 2009. The laser was tested three times in five-minute durations using two separate laser power meters, and created an output 1W peak and 940 mW (+/- 20 mW) average power.
In the U.S., the Congressional Research Service notes that a ban could "pose significant challenges because these devices are widely available at low cost and are used in a variety of applications such as laser pointers, laser levels and laser gun sights." [19] Requiring review or approval of outdoor laser uses.
The Outfit DEC or Laser Dazzle Sight (LDS) is a British ship-based laser. The veiling-glare laser utilizes ultraviolet light and is designed to dazzle by causing fluorescence in the lens of the human eye. There are other such laser weapon systems in development.

A laser warning symbol. Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations.
Another military use of lasers is as a laser target designator. This is a low-power laser pointer used to indicate a target for a precision-guided munition, typically launched from an aircraft. The guided munition adjusts its flight-path to home in to the laser light reflected by the target, enabling a great precision in aiming.
