The power-driven laser pointer has many advantages

The Navy uses expensive weapons and ammunition to strike back at targets—they are incoming missiles, small assault boats, and coastal defense systems—even if these targets are destroyed, it will only cost the enemy very little. Said at a seminar at the Marshall Institute. “This is not an affordable game. If you need to continue this…

How did the reflective ultra-short throw laser projection evolve?

How can the projector overturn the TV? If you look at the performance of traditional projectors, there are actually many shortcomings. The first is the problem of the laser pointer. The traditional projector lens needs a long distance to achieve a large screen, so users need a lot of space to use. Therefore, many meeting rooms…

Application and development of high-power laser pointer welding technology

Welding is the most widely used and most important method for permanent connection of materials. It has unique advantages in improving material utilization, reducing structural weight, and reducing costs. laser pointer welding is the fastest-growing welding method in the past ten years. It uses a focusable and adjustable high-energy density laser beam as a heat source to…

Turkey develops two continuous wave anti-drone laser pointer weapons

According to reports, the Turkish Communication Security Research Center has completed the development and testing of two laser pointer systems and plans to equip the Turkish Army. It is understood that both laser systems use continuous wave lasers with an operating wavelength of 1070 nanometers (±10 nanometers). The first laser system is called Armol Vehicle Laser System…

Human Cosmic Hearing Aid Laser Pointer

However, the space-time distortion caused by gravitational waves is very small. For example, when GW150914 reaches the earth, the strain is only 10-21. LIGO is an L-shaped modified Michelson interferometer, and its structure is shown in Figure 1. Two 4 km long interference arms are perpendicular to each other, and the arm length change produced…

Laser pointer interference gravitational wave detector

Gravitational waves were directly detected for the first time after Einstein predicted the 100th anniversary of gravitational waves. The specific time is September 14, 2015. LIGO’s two probes in Louisiana and Washington state detected the merger of two black holes with 29 and 36 solar masses believed to be 1.3 billion years ago (GW150914 )….

Researchers develop new laser pointer detector

Recently, a group of international researchers developed a new instrument for the laser pointer Interference Gravitational Wave Observatory (LIGO), which can remove quantum noise and expand the detector’s detection range in the universe. This new device called “quantum vacuum squeezer” helped LIGO reduce this confusing quantum crack phenomenon and expand the detection range of the detector by…
