Laser weapons are directed energy weapons that use powerful directional laser beams to directly damage or disable targets. It is a high-tech new concept weapon that uses the huge energy carried by a high-brightness laser beam to destroy or kill enemy aircraft, missiles, satellites, personnel and other targets. Strong laser weapons have incomparable advantages over other weapons. Strong laser weapons have the advantages of fast speed, high accuracy, long interception distance, rapid fire transfer, no interference from external electromagnetic waves, and strong continuous combat effectiveness. Because of this, many Western countries such as the United States, Russia, Britain, Germany, France, and Israel are actively developing strong laser weapons. After more than thirty years of research, laser weapons have become increasingly mature and will play an increasingly important role on future battlefields.
Currently, Russia is in a leading position in theoretical research in the world, and the United States and Israel are in a leading position in the application of laser weapons. Only China is silent. In the minds of the Chinese people, China’s weapons are backward. Is this really the case? not necessarily. In fact, China's laser weapons are ahead of the United States and ranked first in the world. There are two major bases for this statement:
First, the over-the-range offensive lidar developed by China is powerful! It not only has the function of a thousand-mile eye, but also has the power of a lightning-fast and extremely powerful thousand-mile spear! It can destroy the target directly the moment after the lidar detects it! Lidar is an active radar and has more advantages than traditional electromagnetic radar. Stealth aircraft will undoubtedly be missed by his clairvoyance. After an old military expert learned that a target thousands of miles away had been destroyed by lidar, he was so excited that he burst into tears and shouted to the sky, this is a weapon developed by the Chinese! It is the best weapon in the world! This is the most sophisticated acupoint weapon in the world! This led a well-known Chinese strategic military expert to proudly declare in the media: Does the United States dare to attack China? If its stealth planes come to bomb China, one of them will be shot down and no one will be left.
2. The United States is too assertive and China is too modest. If China lags behind the United States in traditional missile technology, it is undeniable because China started late, has poor basic industry, and has strict restrictions on China's military industry by Western countries. However, in terms of the military technology application of emerging lasers, since our starting point is not much different from that of the United States, China's Professor Ma Zuguang is the real world authority in the military technology application of emerging lasers, so our research is in a leading position in the world. If it were not for the involvement of military secrets, I am afraid that the Russians would never have won the Nobel Prize in 2000. In theoretical research on quantum dot lasers, China has long been in the world's leading position. China's ultra-powerful solid-state lasers It is world-class. The laser beam it emits can achieve an energy density of 35 K joules per square centimeter at a distance of 3,000 kilometers. This energy density is nearly one order of magnitude higher than the damage threshold necessary to attack missiles. Based on this rough calculation, the effective lethality of China's attack lidar exceeds 30,000 kilometers.
China’s attack lidar contains the world’s five most cutting-edge core technologies:
1. Breakthroughs in laser material research,
2. Laser radiation materials Breakthroughs in physical mechanism and imaging map research
3. Breakthroughs in one-time fast tracking positioning control technology
4. Breakthroughs in high-density energy reversible conversion carrier materials
5. Breakthrough in laser imaging technology.
Let’s take a look at the characteristics of laser weapons first. Strong laser weapons are primarily used to counter missiles. Its most prominent advantage is that there is no interception process and it is fast. But it also has big drawbacks.
Mainly include:
a. 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, etc. , this defect determines that its ground application is only suitable for short-range point defense systems. The use of space-based missiles against air-to-air missiles is limited to certain conditions. Can the problem be mounted on the limited space of the aircraft? The reaction time is sufficient, only lasers have such reaction time!
b. Limitations of high-precision tracking and aiming systems. The laser beam angle is very small. In order to achieve combat, it must be accurately aimed at moving targets. For this reason, an optical tracking system must be used. It is affected by the atmosphere like laser weapons, and it also requires the system to have good dynamic tracking characteristics.
c. The use of combat in the atmosphere is limited by the combat distance, and it is difficult to intercept tactical ballistic missiles by relying on a single station.
ｄd. The damage effect is uncertain. The laser killing effect is greatly affected by the characteristics of the target material. Some materials cannot be destroyed, so it is difficult to judge. New methods for evaluating the killing effect need to be researched. Therefore, laser weapons are difficult to use as the main anti-missile combat system, but they can be used in space-based applications to achieve long-range interception. The United States has determined plans for airborne laser weapons to be used to intercept tactical ballistic missiles during the boost phase. Some research reports predict that the U.S. Air Force in the 21st century may be equipped with airborne and spacecraft-borne laser weapons. In terms of ground-based applications, laser weapons can be used in short-range point defense anti-missile air defense systems to achieve terminal interception. The United States has developed a prototype of a high-energy laser weapon system, which through tests has demonstrated the ability to destroy high-speed flying targets; the United States and the Netherlands have cooperated to develop a tactical laser weapon system that replaces goalkeepers; the United States and Israel have jointly launched the Nautilus Project, using laser weapons to intercept Katyu Sa rockets. It can be seen that the prospect of tactical laser weapons for low-altitude anti-missile weapons is optimistic.
From this, it can be seen that laser weapons will be launched from various platforms such as ground-based, ship-based, air-based, space and even mobile platforms.
Does China have its own airborne laser weapons? It is said that the code name is \"**\".
Airborne short-range laser defense system: First, a passive infrared search and tracking device is used to detect the tail flame emitted by the flying air-to-air missile, roughly determine the target position, and then turn on the multi-beam laser illuminator (usually using a diode A pumped solid-state laser (wavelength 1.06 μm) illuminates the incoming missile body. This process of converting the missile tail flame detection into the missile body detection is called the hard projectile handover process, and is converted into a laser illuminator active tracking process. Then the high-resolution infrared imaging sensor accurately determines the position of the missile tail flame, thus entering the tracking recovery process. At the same time, the high-resolution infrared sensor detects the cone-shaped head of the missile in flight and uses the multi-light speed laser beacon ( Diode-pumped solid-state lasers are also usually used to aim at the conical head and measure the reflected laser beam. The optical distortion caused by aircraft vibration, atmospheric turbulence and heating of the laser optical device is obtained, and then the correction parameters are input to the adaptive reflector. Optical distortion correction to compensate for the impact on laser defocus and aiming accuracy. After completing the adaptive compensation, it emits a 1.3μm oxygen-iodine chemical laser killing beam with a wavelength of several seconds to destroy the target's fuel tank.
