"I don't think it's too much to worry about first, just add a laser weapon system to the sky city, without any weapon system, our sky city may soon be destroyed by space junk, and the huge amount of money will be completely wasted, and the personnel in space and so on are also facing huge dangers."

Li Fu thought about it for a long time, and finally decided to install a laser weapon system for Sky City, which has a huge investment and is a bridgehead for his Fuyun Group to enter space, if there are no protective measures, it is really unsafe.

The others also nodded after hearing this, Li Fudu had already made up his mind, what else did everyone have to object.

"I think this matter is listed in the company's top secret, and our weapon system should not be exposed as much as possible, after all, there will still be a lot of trouble, and after our company can obtain a license for weapon manufacturing in the future, it will be reasonable and legal to expose it again."

Chen Bin thought for a long time and then added, whether things in outer space should abide by the law or not, there is no explanation yet, so it is better not to make a noise about this matter first, the law will gradually improve in the future, the company will continue to develop, maybe in the future you can get a license to produce and manufacture weapons.

You must know that now Fuyun Group has obtained the license to produce aerospace aircraft, in addition to the aerospace aircraft used to travel to and from space, in fact, the more important thing is to fight, once the situation changes, the aerospace aircraft can soon be converted into aerospace fighters, used to defend the interests of China.

"Well, it must be classified as top secret, and the fewer people who know about it, the better."

Everyone else also nodded, the current Fuyun Group has a lot of high-tech in its hands, plus various foreign policies, etc., and the interests are very important, so all kinds of internal information have been classified, and many secrets are only known to a few people.

The strict separation system of administration and scientific research is not only these secrets, but also the non-scientific research personnel in the company cannot enter the scientific research center at all, and the purpose of all this is naturally to protect the company's science and technology.

With a decision, Li Fu first suspended the Sky City plan and led the team to prepare to research the laser weapon first.

The question of why lasers can be used as weapons must be confusing to many people. Many times when we are attracted to something's amazing ability and dazzling appearance, it is often easy to lose sight of the most basic "why".

Essentially, a laser is a light source, just like ordinary light. To understand how a laser can become an offensive sword in the human hand, it is first necessary to figure out how it differs from the light source in everyday life.

Let's start with the familiar incandescent lamp, which emits a light that scatters in all directions, like ripples on the surface of water, with "peaks" and "valleys", or highs and lows.

Assuming our eyes are capable of perceiving every ray of light from an incandescent lamp, you will see a lot of "peaks" and "valleys" passing by you. They actually have different frequencies and different colors, but they are mixed together to give a picture like the white that we see with the naked eye as the sun appears.

Next, let's recall the "household appliances" that were commonly used before the 90s - flashlights. Is the light emitted by a flashlight more concentrated than that emitted by an uncovered incandescent lamp, and most of the light is concentrated in the same direction according to the direction of the flashlight in your hand. However, these relatively concentrated rays still have different frequencies, and they are also white due to a mixture of colors.

Compared to the light of incandescent lamps and flashlights, the laser is much more concentrated, and its light has the same wavelength and a single color. The peaks and valleys of laser light waves are synchronized waves, which means that different light waves can run in parallel without interfering with each other.

This light is emitted in only one direction, so it can be tightly packed and remain focused even after traveling long distances. Lasers can produce beams of light with extremely high energy that is 1000-1,000,000 times more powerful than the energy of ordinary incandescent light rays.

Different lasers can produce light with different wavelengths, from infrared to visible to ultraviolet. It is now known that light is actually a moving energy. Because lasers can produce very dense energy and can be transmitted over long distances with minimal loss, they can project large amounts of energy onto objects over long distances. That's why lasers can be lethal weapons, while incandescent light cannot.

However, for a laser to be generated, its light transmission requires an unconventional method. The English word for laser is LASER, that is, laser, and its name is composed of the English initials of "radiation produced by the amplification of light by stimulated emission", which has fully expressed the main process of making a laser. In other words, lasers need to emit light by stimulating the release of light quanta, or light particles.

To accomplish this process, a laser requires four basic elements: an optical medium, a source of atoms that can release special wavelengths when stimulated, which can be gases, liquids, or solids; energy, mobilizing and pumping these atoms so that they are in an excited state in the laser medium; Reflective mirrors, a complete mirror and a semi-silver-plated mirror, which allow the emitted light to repeatedly bounce back in the resonant cavity of the laser medium and eventually escape; Lenses, most laser emitters are equipped with some kind of lens to focus the beam.

"The essence of laser is actually a process of energy storage and release, because of the particularity of light, what we have to do is to concentrate as much energy as possible to a point, and then release it, this is the essence of laser."

In a laboratory of the research institute that Fuyun Group is located in the source town not long ago, Li Fu, who is dressed in a white coat, has his back to a huge monitor, on which the working principle of laser weapons is being demonstrated.

Li Fu manipulated his virtual machine to outline different things on the display while explaining, there is a lot of scientific knowledge and technology about energy weapons in the seeds of super civilization, and what Li Fu just said is not only the essence of laser weapons, but also the essence of energy weapons.

Accumulating a huge amount of energy, compressing the energy, and finally releasing all the energy at one point, all the energy weapons in the entire universe cannot escape this principle.

"At present, the most important lasers on the earth are the following: solid-state lasers, the laser medium of solid-state lasers is a solid-state crystal, such as the famous ruby laser or yttrium aluminum garnet laser, which can emit light waves with a wavelength of 1.06 microns."

"Gas lasers, gas lasers are a laser medium composed of a gas or a mixture of gases, such lasers include helium-neon lasers or carbon dioxide lasers, which can emit light waves (infrared) with a wavelength of 10.6 microns."

"Excimer lasers, the laser medium of excimer lasers is a mixture of a variety of reactive gases such as chlorine, fluorine and a variety of inert gases such as argon and krypton, argon-fluorine lasers can release 193 nanometer ultraviolet light waves."

"Dye lasers, as the name suggests, the laser medium of a dye laser is composed of a fluorescent dye, such as rhodamine. This laser can tune out different wavelengths of light waves in a certain range, and the wavelength released by the Rhodamine 6G dye laser is generally 570-650 nm. ”

"The carbon dioxide laser, this kind of laser is more special, because it is a powerful infrared laser developed by the military of various countries, which can be used to cut metal, and it is also the most likely to be used to develop laser weapons at present."

On the huge display, pictures flashed by, which explained in detail the working principles of various lasers and the laser light waves that can be generated.

"In fact, there is also a kind of free electron laser, there are many types of these lasers, but in essence, they can be divided into two types, the principle of physical laser and the principle of chemical laser."

With the seeds of super civilization, Li Fu can do anything from a high position, standing on the shoulders of giants, Li Fu often gives lectures to his company's scientific researchers, so the company's scientific researchers are making very rapid progress, otherwise Yu Liang, Chen Bin and others would not have won the title of Huaxia Academician at a young age.

"Brother Fu, I understand, we have to develop laser weapons, in fact, no matter what methods and methods are used, we are actually storing energy, compressing energy, and releasing energy, as long as we can do these three steps well, laser weapons are just very simple things."

The following researcher of Fuyun Group listened carefully to Li Fu's lecture, while constantly thinking in his mind, at this time a very delicate-looking, fair-skinned person like a white man stood up, his name is Bai Cai, is an authentic man, but he is very delicate and very white, so everyone likes to call him "little cabbage".

Although he has the nickname of "little cabbage", Bai Cai is a genius, a high-achieving student who graduated from Yanhuang University, and can quickly stand out in the research institute full of talents, follow Li Fu's side, grow very fast, and now he is one of the core personnel in the company's research institute.

"Little cabbage is right, we just need to grasp the essence of laser weapons, and find ways to work hard in the three directions of energy storage, compression energy, and energy release, laser weapons are actually not difficult for us at all."

Li Fu nodded, the core of the energy weapon is actually so simple, the key is what kind of degree it can do, and it is very simple for an advanced civilization to destroy the planet with an energy weapon.
