In order to solve the laser quantum noise interference, the LIGO experimental group cooperated with the German GEO600 gravitational wave detector project team to use compressed light technology to weaken the quantum noise. Now these compressed light technologies have been officially used in the GEO600 interferometer, and a preliminary trial has been conducted in the…
The Number Of Photons in The Red Laser Pointer of The Detector
LIGO’s two interferometers are located in Livingston on the south coast of the United States and Hanford on the northwest coast. Each interferometer is composed of two 4km long vacuum steel pipe arms that are perpendicular to each other in an L shape. Many finely processed mirrors are installed at the ends. When a laser pointer passes…
Laser Detection Of Gravitational Waves Is Questioned
The laser interferometer gravitational wave observatory (LIGO) announced that the third detection of gravitational waves was not more than one month. Recently, the United States “Wired” magazine reported that several independent physicists had laser The laser pointer data raises questions. Danish physicist Andrew Jackson and four others jointly wrote to Quantum Magazine that after detailed analysis of…
U.S. Navy Tests Laser Weapon System To Accurately Target Drones
The US Navy conducted a laser pointer weapon test in the Persian Gulf and struck a drone with precision. The laser weapon system, abbreviated as LaWS in English, is deployed on the US military amphibious carrier “Ponce”. The captain of the ship, Wells, said: “This system is more accurate than bullets. This is not a highly specialized…
Combined Lasers Are Used To Explore Topological Defects
The interacting laser circle is a new laser pointer model that can be used to explore topological defects and disordered structures in seemingly unrelated systems. If the molten iron is cooled slowly, the spins of the electrons can gradually be aligned in the same direction, thereby generating a strong magnetic field. However, rapid cooling of the molten…
Prospects For The Application of Laser Underwater Detection and Target Recognition
Recently, the European Defense Agency (EDA) commissioned a joint study by the Swedish Defense Research Agency (FOI) and the St. Louis-Fade Institute (ISL) to show that laser pointer technology applications can be used as a supplement to existing sensors (sonar) for underwater targets Detection and identification, especially in shallow waters or areas with complex terrain, such as…
Semiconductor Gain Material Growth Laser Pointer Gain Chip
Researchers at the Shanghai Institute of Applied Physics of the Chinese Academy of Sciences have recently proposed a new mechanism for generating high-brightness, fully coherent radiation based on storage ring light sources. Studies have shown that this operating mechanism can make full use of the characteristics of the storage ring electron beam, and can achieve…
Set A New World Record For Laser Pointer Monochromaticity
A new world record in laser monochromaticity. German and American scientists jointly created a laser with a spectral line width of only 10 milliseconds (1 millihertz is 0.001 hertz), setting a new world record for laser pointer monochromaticity. According to a press release issued by the German Federal Institute of Physics and Technology, this is by far…

At the same time, in the field of laser pointer technology and key devices, researchers have not stopped. Realize the widest spectrum dark soliton pulse output. Ultrashort pulse fiber laser has the characteristics of easy operation,…
Phase Modulated External Cavity Diode Red Laser Pointer
For a typical active fiber laser pointer, the comparison between the measured thermal load and the simulated thermal load extracted from the simultaneous distributed temperature measurement inside the optical fiber amplifier is given. In order to accurately predict the longitudinal temperature curve, it is assumed that there is only an additional loss of 2dB / km,…
