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 ...
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]
Scintillation is also a problem in development of weaponized lasers, such as the airborne laser being developed to intercept intercontinental ballistic missiles. According to an article published on May 3, 2006, in The New York Times , research is being conducted at the laboratory into how to use ground-based lasers to disable satellites ; that ...
Dazer Lasers use a "GreenStar Laser" (US Patent and Trademark Office provisional patent application no. 61/348,312), which is a diode-pumped solid-state (DPSS), 532 nm (green), Class IIIb laser that produces maximum power of over 750 mW without having to increase the same laser's size. [4]
(Reuters) - Portland Police said on Tuesday some of its officers had been targeted with a "powerful green laser" capable of causing permanent eye damage when some 200 protesters marched on the ...
Reports of lasers illegally pointed at aircraft in flight rose to a new high in 2023, the latest spike in a series of steady increases during the past decade. ... Green laser pointers are the most ...
Green DPSSLs are usually around 20% efficient, although some lasers can reach up to 35% efficiency. In other words, a green DPSSL using a 2.5 W pump diode would be expected to output around 500-900 mW of 532 nm light. In optimal conditions, Nd:YVO 4 has a conversion efficiency of 60%, [1] while KTP has a conversion efficiency of 80%. [2]
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.
