Chapter 569

Deep space laboratory also has a deep accumulation in the field of optics. Like Xiong Antai, Zhang hanxiu also considered space weapons. His idea is laser weapons. Whether in science fiction movies or in reality, laser weapons are big killers.

"Like the electromagnetic railgun mentioned by the boss, laser weapons can also be classified into energy weapons, and our company's technical advantage is that we have a nuclear fusion reactor, which can provide stable and continuous energy.

Moreover, our company also has a very outstanding performance in the field of materials science. We are leading the world in the field of materials such as superconducting materials and high-energy batteries, which provides a solid foundation for our research and development of laser weapons!

Laser weapons in space because there are no restrictions in the atmospheric environment, so there is no only limited use on the earth, can not carry out all-weather combat embarrassing situation, can launch attacks at any time!

"Origin", give us a brief introduction to laser weapons. " As he continued to introduce, Zhang began to be lazy again.

His words also made everyone laugh. This guy is lazy and steals so openly. "Origin" as the company's artificial intelligence, takes charge of a large number of tasks of the company.

For example, it does all kinds of meeting records and related paperwork of the company now. When meeting various problems related to the company, we will call it to introduce it to you when we are not clear about it. However, the task assigned by Zhang hanxiu is too simple for it, so it will not refuse such work.

"Good, director Zhang! Science popularization task begins.

Laser weapon (English: laserweapon) is a kind of weapon that uses high-energy laser to accurately shoot long-range targets or to defend missiles. It is divided into tactical laser weapons (thel) and strategic laser weapons.

It can play a unique role in photoelectric countermeasure, air defense and strategic defense.

The disadvantage of laser weapon is that it can't fight all-weather and is limited by fog, snow and heavy rain. Moreover, the laser emission system is a precision optical system, which is also seriously affected by the atmosphere, such as the absorption of energy by the atmosphere, energy attenuation caused by atmospheric disturbance, thermal halo effect, turbulence and attenuation caused by beam jitter.

Because laser weapons need a lot of electric energy, it is difficult to realize large-scale application before the problem of energy storage equipment is difficult to be miniaturized (such as high-energy batteries).

Of course, as director Zhang said, the above two problems have little impact on the laser weapons that our company will develop soon.

Because our company's requirements for laser weapons are to be used in space operations, that is, they tend to use strategic laser weapons. There are no such interference systems in space.

As long as our company's nuclear fusion reactor technology is further advanced and can be miniaturized and mobile, the energy problem will not be a problem, and the high-energy battery level of our company can initially support strategic laser weapons.

The so-called tactical laser weapon uses laser as energy. It directly kills enemy personnel, destroys tanks and airplanes like conventional weapons, with a striking distance of 20 km. The main representatives of this kind of weapon are laser gun and laser gun, which can send out strong laser beam to attack the enemy.

The strategic laser weapon is a kind of laser weapon used to attack strategic missiles or satellites, with a range of several hundred to several thousand meters and a laser power of more than ten million watts. This is the research and development direction of our company. In a large-scale environment like the universe, the higher the range and power of laser weapons, the better!

If we can develop it like the main laser weapon of the death star in Star Wars movies, then our company will have enough confidence in the face of danger!

There are two aspects in laser damage: one is perforation, the other is spallation.

The so-called perforation is that the high-power density laser beam makes the surface of the target melt rapidly, then vaporizes and evaporates, the vaporized material ejects outward, and the shock wave is formed by the recoil force, and a hole is pierced in the target material.

The so-called spallation is that after the laser energy is absorbed by the target surface, the atoms are ionized to form an isoplasmon "cloud". The "cloud" expands and ejects outward to form the stress wave propagating to the deep. The reflection of the stress wave causes the target to be pulled apart, resulting in "spallation" damage.

In addition, the plasma "cloud" can also radiate ultraviolet or X-ray, damaging the target structure and electronic components.

The damage mechanism of laser weapon is:

1. When the target is irradiated by high-power laser, the surface material absorbs heat and is heated to produce softening, melting, gasification and ionization. When the deep temperature of the target material is higher than the surface temperature to accelerate the gasification, the internal pressure increases and the explosion occurs.

2. Mechanical failure. When the laser irradiates the object to produce vaporization and ionization, the plasma ejects outward at a high speed, and the recoil force will make the target deform and fracture.

3. Radiation damage. Plasma can radiate ultraviolet or X-ray, and destroy the electronic components inside the target.

The characteristics of laser weapons are: concentrated energy, fast transmission speed, high hit accuracy, fast transfer firepower, anti electromagnetic interference, can be repeatedly used, high combat efficiency cost ratio.The laser weapon is mainly composed of a laser which produces a light source and a beam director which has the functions of tracking, aiming and emitting.

High concentration of laser, energy is also very concentrated. For example, in our daily life, we think that the sun is very bright, but a giant pulse ruby laser is 20 billion times brighter than the sun.

Of course, the laser is brighter than the sun, not because its total energy is larger than the sun, but because its energy is very concentrated. For example, a ruby laser beam can penetrate a 3cm thick steel plate, but the total energy is not enough to cook an egg.

As a weapon, laser has many unique advantages. First of all, it can fly at the speed of light, 300000 kilometers per second, which is not the speed of any weapon. Once it's aimed, it hits the target almost immediately in no time, regardless of the amount of advance.

In addition, it can concentrate more than one million times the energy of nuclear weapons in a very small area and in a very short time. It can also change its direction flexibly without any radioactive pollution.

With so many advantages, I think director Zhang's suggestion is correct!

However, its research and development task will not be very easy, the charging speed determines the firing speed of laser weapons, the high temperature resistant materials determine the firing times of gun barrel, and the performance requirements of aiming detection equipment and other equipment are also very high, these problems need to be solved!

Only when these shortcomings are solved, laser weapons used in our company's future spacecraft can be regarded as a mature space weapon!

I have finished my introduction. Thank you very much
