Rumor has it that LiDAR integration is just one of the things we can expect from the theoretical iPhone 12 when it comes out later this year. Naturally, Apple's probably got all kinds of weird new ...
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.
For example, a laser sight is a small, usually visible-light laser placed on a handgun or a rifle and aligned to emit a beam parallel to the barrel. Since a laser beam has low divergence, the laser light appears as a small spot even at long distances; the user places the spot on the desired target and the barrel of the gun is aligned (but not ...
Protective eyewear is typically required where direct viewing of a class 3B laser beam may occur. Class-3B lasers must be equipped with a key switch and a safety interlock. Class 3B lasers are used inside CD and DVD writers, although the writer unit itself is class 1 because the laser light cannot leave the unit.

Expected to be finished by October, Hilton Head is installing Rectangular Rapid Flashing Beacons to alert drivers of pedestrians at crosswalks. Here’s where they are going.
Projection, life sciences, forensic analysis, spectroscopy, eye surgery, laser light shows. The lasing medium is a semiconductor chip. Frequency doubling or tripling is typically done to produce visible or ultraviolet radiation. Power levels of several watts are possible. Beam quality can be extremely high- often rivaling that of an ion laser.
A New York teen lost vision in his left eye moments after powering up a "defectively designed," Chinese-made laser pointer he purchased on Amazon, according to a lawsuit against the retail behemoth.
