Compared with the ABL, burning laser Weapon will encounter many technical difficulties, if the power density is unable to meet the demand, it is likely to face the fate of stillborn.The U.S. missile defense agency is continuing develop the technical high power laser weapons investment.In fiscal year 2019, the defense agency will select one of the most successful type, according to the proportion.It is reported that, if the deployment of laser weapons successfully, anti missile UAV Will take the boost phase missile task.At present, the directional director of the U.S. missile defense agency James Sunning said that the current UAV laser anti missile boost phase development problem is to improve the power to weight ratio, in order to make it stronger

The Ideal Power of Laser Weapons Is Still a Hard Work

.In 1962, at Lawrence Livermore National Laboratory in California, physicist John Nuckolls proposed using high powered laser to achieve controllable nuclear fusion.Since then, the Lawrence Livermore laboratory has been pursuing this concept, the power of the laser they used were also growing. This is a complex system that can be issued at the same time. National ignition device is developed by the United States scientists, it was the world's largest laser nuclear fusion device. It is reported that this is known as "artificial sun" device which can produce similar stellar core temperature and pressure.

In industry, the 200mw Laser Pointer is used as a saw and a drill.People tend to use laser to machine high hardness materials, such as diamond, or baby pacifier.Low power lasers can be cut and welded plastic; high power lasers can cut and weld metal. Early industrial lasers must have very large figure in order to produce enough energy, but novel solid-state lasers are very small.A small size of laser can produce enough energy to cut a few centimeters thick sheet metal.

The second way is to use the laser continuous irradiation target of 10 to 15 seconds, so as to achieve the same damage effect. However, the weak intensity of the laser can be disturbed by atmospheric activities and weather conditions, and its intensity will gradually decay in the long distance transmission.

Another Problems Need to Be Solved For Laser

Xu Ning believes that 300mw Laser Pointer weapons' ideal power weight ratio should reach 2 to 5 kg / kW level.In contrast, chemical laser weapon "YAL-1A " laser can up to 55 kg / kW, the current synthetic fiber laser weapons and the prototype of DPAL level has reached 35 ~ 40 kg / kw.Zhang Yang believes that from the cold war to the present, the United States has invested a lot of resources development of laser technology, in this respect, they have been a leader of laser weapon in the world.The future of laser weapon power density ratio can achieve 5 kg / kW.

The Bush administration has decided to resume military space laser research, each satellite carrying intercept ballistic missile's laser cannon. In this way, the total number of laser guns in space at the time of the United States to reach at least 4000.The Navy's research shows limits of high energy burning laser beams in coastal waters, and therefore, the effectiveness of laser weapons is limited. The wavelength of the chemical laser is not the best for the coastal environment. Thus, the Navy's high energy laser program changed direction, and in 1995 it stopped working on the feasibility of the chemical laser. The Navy's interest is concentrated in the solid state laser technology, because the application of this technology can make them do not have to deposit high risk chemicals on the ship, but also to avoid the generation of toxic chemicals produced by laser. In order to be able to use laser weapons in the future, the navy has plans to install large power generation equipment on the next generation of aircraft carriers. When the laser weapon developed and improved and produced, it will be deployed and used on these ships.

The air laser cannons is the most popular

Chemical lasers have also be used at air force , the air force airborne laser project aimed at placing giant chemical laser on a 747 aircraft to shot down ballistic missiles. The improved Boeing 747 had its first flight in 2001, but there were no 100mw Laser Pointer cannons mounted on the aircraft to test its aerodynamic effects. The laser was installed at Boeing 747 aircraft, and after several tests, the whole system is expected to achieve goal of Scud missile . By then, the prototype can be put into operation, then, this monster will be the largest laser weapon so far. The launch of the company's tests show that the laser can generate heat from a fixed position to destroy the missile. The next hurdle to cross is to allow the laser to fly at a speed of 1000 kilometers an hour to finish the same work on a plane that is 12 thousand meters above the ground. Airborne laser will carry enough chemical raw materials.

However, due to the high cost of chemical laser system, the army believes that solid laser technology can provide them with a smaller size, enough to install the system. In 2002, a 10 kW solid energy laser system already in operation, the transmitter laser beam cut three pieces of thick plate of about 3 mm within 6 seconds. Solid state laser project has also attracted the attention of the air force, the air force is currently being discussed whether the system to replace its aircraft on the active chemical lasers.

Space laser cannon weapon

The high energy 30000mw Laser weapon is the product of the combination of high power laser weapon and spacecraft. Once the laser weapon found each other it can hit the target immediatelly. Because of its deployment in space, it is a tiger with wings added. Many technical achievements such as laser program are derived from the results of the U.S. military in the cold war period . The US military has been exploring various types of laser weapons.

Laser cannons are the most efficient weapons in PVE. Most of the opinions think that the 200mw Laser Pointer weapon is the best PVE weapons, but the best effective is the difference between. These advantages make laser weapon the best overall performance of the more position . The laser pointer weapon while in use have a lot of difficulty (the most obvious point is on the short distance ), but it can through the corresponding tactics down low adverse effects (such as we are familiar with the distance a kite tactics). To understand more clearly of various burning laser pointer weapons, we need to introduce the following concepts: duration of fire, fire transfer speed, fire interruption interval.

According to the "Aerospace Daily" reported on July29, the U.S. missile defense agency (MDA) did not give up the interception boost phase ballistic missile by using space based laser weapon, they planto develop a high altitude long endurance UAV.

The space based laser anti missile plan

Since the mid-90s of the 20th century, the US has initiated the airborne burning laser (ABL) program, the kinetic energy interceptor (KEI) plan, network center airborne defense unit NCADE etc. a series designed to boost phase intercept the missile defense plan,ABL program was undoubtedly the most sensual with high-energy laser .

In 1996, the U.S. Department of defense give the ABL project team allocated $1 billion 100 million to develop the experimental set of ABL weapons systems. ABL testing machine YAL-1A improved from Boeing 747-400f aircraft, loaded with the latest development of the airborne laser energy weapon, used to destroy in takeoff boost phase state of tactical ballistic missile, the enemy missile to destroy the enemy airspace and territorial. The ABL aircraft equipped with the system has a megawatt class chemical oxygen iodine laser (coil), infrared tracking / high speed target acquisition system and high precision 5000mw Laser target beam tracing control system.

The future of laser weapon

Although the airborne Attack Laser Pointer program quiet down, but in recent years, the U.S. missile defense agency has been seeking a new generation of airborne lasers which can be carried by the high-altitude uav. The project aims to seek a new way, will be a compact and high efficiency of laser weapons are integrated into the high altitude long endurance UAV will eventually be used to intercept in boost phase ballistic missile. Due to the high altitude long endurance without UAV flight height is very high, so it can avoid the adverse effects of atmospheric environment and the clouds of laser weapons used to the maximum extent.

In 2004, ABL destroyed a ballistic missile successfully. However, after Obama took office, he paid more attention to the development of 300mw Laser Pointer technology. December 2011, the U.S. Department of defense decided to terminate the ABL airborne laser research and development projects. Although the ABL program has been terminated, but through the implementation of the project, the United States in the field of laser technology, energy preparation and beam control were obtained great progress, this is the new airborne laser development has laid a solid foundation.
