The emitters are usually lasers, making what is termed a laser dazzler. Most of the contemporary systems can be carried by a person, and operate in either the red (a laser diode) or green (a diode-pumped solid-state laser, DPSS) areas of the electromagnetic spectrum. The green laser is chosen for its unique ability to react with the human eye. [5]
The first laser, invented by Theodore Maiman in May 1960. Nd:YAG laser: 1.064 μm, (1.32 μm) Flashlamp, laser diode: Material processing, rangefinding, laser target designation, surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam). One of the most common high ...
Door breaching is a process used by military, police, or emergency services to force open closed or locked doors. A wide range of methods are available depending on the door's opening direction (inward or outward), construction materials, etc., and one or more of these methods may be used in any given situation.

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.

Copper vapor laser. A copper vapor laser (CVL) uses vapors of copper as the lasing medium in a 4-level laser. [1] It produces green laser light at 510.6 nm and yellow laser light at 578.2 nm. The pulse width is typically from 5 to 60 ns, and peak power from 50 to 5000 kW. Its pulse repetition frequencies can be 2 to 100 kHz.
Using lasers, scientists illuminated the tiny water droplets — and possibly pathogens — that are ejected into the air when a lid-less toilet is flushed. Green lasers reveal you should close ...
