When a dog finds a shaking spot, there is nothing more important in the world than catching this spot. Unfortunately, this sloshing light spot is a massless photon beam that cannot be captured. In fact, constantly chasing the light spot may eventually interfere with the dog’s brain. The animal behavior professor at the Cummings School…

R&D Institutions Develop Laser Pointers According to Demand
Although the world’s laser weapons have developed rapidly in recent years, the overall situation is still in the stage of moving towards actual combat applications, especially high-energy laser pointer weapons such as laser guns, because there are still some problems that restrict its battlefield applications. Although chemical and solid laser weapons have the best overall performance and…
Self-designed And Built Driving Laser Pointer Shaping System
Each laser pulse of the light source can generate more than 100 trillion photons, and the wavelength can be completely continuously adjusted in the extreme ultraviolet region, with complete coherence. The pulse length can be selected between femtosecond (1 femtosecond equals one trillionth of a second) and picosecond mode, and can also be operated in…
Analysis of The Progress of Laser Weapons Can Form Unlimited Firepower
Laser weapons have played a leading role in science fiction for decades. At present, this weapon has finally become a reality in the US military, although its power is slightly worse than in the movie. The lightsaber is a weapon favored by the Jedi Knights in the “Star Wars” series of movies, but it seems…
U.S. Successfully Conducts Laser Weapon Attack Drone Test
The US Army installed a low-power laser weapon on the “Stryker” wheeled armored vehicle, and successfully conducted a laser weapon attack on the drone. The “Stryker” armored vehicle is equipped with a new “mobile expeditionary high-energy laser” (MEHEL 2.0) system that increases its power from 2 kW to 5 kW. In the test, laser weapons…
New Wavefront Measurement Method For High Power Laser Device
With the development of high-power laser devices, people have higher and higher requirements on the output capability and beam quality of the device, and also put forward new requirements for light field measurement. At present, the direct imaging method can only obtain the intensity distribution of the near and far fields of the beam on…
How to Guarantee The Stability And Reliability of Semiconductor Laser Pointer?
Semiconductor lasers are a class of lasers that have matured earlier and developed faster. Due to their wide wavelength range, they are simple to manufacture, low in cost, and easy to mass-produce, and because of their small size, light weight, and long lifespan, the variety has developed rapidly and applications wide range. Due to the…
Laser light emitting area is smaller
In automotive lighting applications, currently world-renowned car brands such as BMW and Audi are making efforts to apply this technology to new products. At the same time, laser pointer lighting is a “point light source”, and it is expected to be integrated with optical fiber technology in the future. I believe that the two can derive a…
New vortex laser can increase data transmission rate by ten times
A new optical-based communication tool can transmit data in a fast circular motion like an eddy current. This optical advancement described in a study published recently in the journal Science may become a core component of the laser pointer for next-generation computers to meet the growing demand for information sharing in human society. It may also eliminate…
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…
