Scientists use lasers to focus on various materials to stimulate shock waves, electromagnetic radiation, etc., to simulate the nuclear test environment and conditions; radiation-free fusion power generation has broad application prospects and can replace existing nuclear fission power generation, clean and safe, and resources rich. It can be said that laser pointer focused shooting is an important…

Control and Change can Smoothly Guide the Green Laser Pointer
So the question is: how to place and fix such a small target? How to achieve a high vacuum environment? We made a set of structures similar to a mechanical arm called a target frame, which can fix the target on its specific fulcrum, and place the fulcrum in the center of the target chamber…
Laser Pointer Shooting Requires A Certain Size
In addition, physical experiments have strict requirements on the spot size and contour focused on the target. In many cases, laser pointer shooting requires a uniform spot with a certain size (such as a size of about 0.5mm), and the focal spot focused by the lens is generally less than 0.05mm, so beam control technology (usually inserted…
Blue-green Laser Pointer Opens up New Ways for Submarine Underwater Communication
For a long time, how to maintain communication with the outside world has been a worldwide problem. The application of the blue-green laser pointer opens up a brand-new technical approach for the realization of submarine underwater communication. The reason why sea water appears blue-green is because sea water absorbs other colors of light in the spectrum. In…
Laser Pointer Helps Submarine Become the Protagonist of Naval Warfare
For a long time, an important reason restricting submarines to become the protagonists of naval warfare is that they cannot rely on electromagnetic waves to communicate effectively underwater. In the future, with the development of underwater communication technology represented by blue-green laser pointer communication, the era of “diving the sea” may be approaching. In fact, in addition…
US Field Test Mobile High-energy Laser Weapon System
The commercial drones operated by the “Islamic State” complicated the Mosul war. The grenade and small bombs they dropped caused the Iraqi army to escape. In response to the increasing threat from the enemy’s “Eye of the Sky”, the US Army conducted field tests on vehicle-mounted laser weapons that intercepted drones. In a 10-day exercise…
The United States Uses Optical Technology to Make Hidden Targets Nowhere to Escape
American physicists have developed a simple optical technique for tracking blurred or hidden targets. This method uses random light signals to detect moving targets obscured by smoke, clouds, or other scattering media. The researchers claim that this technology can not only be used in the field of military and civilian surveillance, to overcome the limitations…
Strength of Green Laser Pointer Based on Reflected Signal of Object
A statistical method was developed to enable them to distinguish the light waves reflected from the moving target and scattered by the scattering medium at the frequency of the light wave. However, this method is only applicable when the target and the scattering medium are moving at different speeds, which means that they will return…
Laser Weapons Are Widely Developed
In fact, laser weapons are a kind of directed energy weapons. According to different operational purposes, it can be divided into two categories: tactical laser weapons and strategic laser weapons. Among them, tactical laser weapons use laser as energy to directly kill enemy personnel, tanks and planes like conventional weapons, and the strike distance is…
The World’s Largest X-ray Laser EmitsLaser Pointer Pulses For The First Time
On Thursday, local time, the world’s largest X-ray laser emits laser pulses for the first time in Hamburg, Germany-it can generate a pulsed laser with a wavelength of 0.8nm per second. The European X-ray free electron laser pointer with a length of 3.4 kilometers (2.1 miles) will be officially put into use in September. When operating normally,…
