Laser is another major invention of human beings after nuclear energy, computers and semiconductors since the 20th century. It is called "the fastest knife", "the most accurate ruler" and "the brightest light". The atom is excited by the radiation, hence the name laser pointer.
Lasers have been seen by humans to date, including the brightest of the light emitted by light sources in nature. Its brightness is 5 billion times that of sunlight, and it is emitted in one direction. The divergence of the beam is extremely small, almost parallel. The energy of the laser is not very large, but because of its small range of action, its energy density is very large, and a large amount of energy can be collected in a short time.
The development of laser not only revitalizes ancient optical science and optical technology, but also has unlimited application prospects in the field of science and technology. The penetration and influence of lasers into the natural sciences has promoted the development of various disciplines and contributed to the formation of many new disciplines. It can be said that laser technology is one of the most active fields in modern science and technology.
According to the British "Daily Telegraph" report, Russia is currently developing laser pointer death rays that can aim and destroy space objects.
According to reports, researchers at the National Aerospace Corporation's affiliates have begun researching laser cannons, the size of which is equivalent to a telescope that will focus on space debris that poses a threat to nearby spacecraft in low Earth orbit. This kind of weapon is expected to gradually evaporate space debris through laser ablation. Laser ablation does produce a lot of heat, causing objects to evaporate or turn into plasma.
It is reported that Russia is not only launching laser pointers to launch laser pointers in space. Earlier this year, it was reported that the country had already produced laser weapons that could be carried on aircraft as part of the anti-satellite system.
