Researchers at Washington University in St. Louis have found a way to provide photons or light packets according to their instructions. The researchers used the generous energy state of a light domain to create photons in their laser pointer system so that they travel in a consistent pattern, clockwise or counterclockwise. For all laser systems and applications…

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 )….
Circular beam semiconductor side emitting laser pointer
The semiconductor laser has been widely used since its birth in 1962, but it still has a much criticized shortcoming, that is, a large divergence angle and an elliptical light emission. Usually the vertical half-angle divergence angle is greater than 30°, and the horizontal direction is about 10°, which results in lower beam quality and…
New breakthrough in high-density data storage ultrafast laser pointer
It is reported that laser-based data storage and retrieval technology will increase the storage capacity of traditional optical discs, such as DVDs and Blu-ray discs, without requiring special preparation steps. This scalable technology uses the 3D volume of the optical disc to store information in a multi-level structure, and the ultra-fast laser pointer is used to maintain…
Interpretation of Femtosecond Laser Pointer Operation Characteristics
Femtoseconds can also be called femtoseconds, which is a unit of measurement for marking the length of time. Taking 1 second as a reference, 1 femtosecond is only one quadrillionth of a second. It can be seen that femtoseconds represent a very short time. Even if light can fly 300,000 kilometers per second in a…
The rapid development of UV laser pointers increases cooling requirements
As we all know, the higher the temperature control accuracy of the ultraviolet chiller, the smaller the water temperature fluctuation and the more stable the water pressure, thereby reducing the generation of bubbles, causing cavitation and vibration to the internal pipeline of the laser pointer, protecting the laser and extending its service life. Teyu CWUL and…
Performance characteristics of fiber laser pointer cutting machine
1. The key components of the series products have undergone CAE analysis, modular design, process manufacturing, and assembly processes. The assembly quality is guaranteed. Scrap cars can be discharged from the left or right. 2. It adopts aviation metal die-cast aluminum beam, special heat treatment, light weight, good rigidity, and stable performance under high-speed operation….
Technical performance requirements for ultra-high-speed laser cladding
Ultra-high-speed laser cladding technology is mainly used to improve the wear resistance, corrosion resistance, high temperature resistance, and oxidation resistance of the surface of the parts, so as to achieve the goal of surface modification or repair, and meet the requirements for the specific performance of the material surface. The ultra-high-speed laser pointer cladding technology essentially changes…
The Laser pointer pointer is not a toy
The pointer of the laser pointer is not a toy! The course was taken home to an elementary school area in Wisconsin in the fall of 1996. A 16-year-old girl was used as a prank laser pointer, illuminating her eyes. She experienced two brief exposures, one during the pom pom program and the other while…
What is the brightness of the laser
How bright? That is purely subjective. SureFire scientist Dr. Peter Hauk (Peter Hauk) is engaged in industrial Laser pointer research at Newport Corp.. Xingang is a global pioneer in the field of laser products and development. He cannot tell how bright the green laser is. “How old is the eyeball? Twenty? Thirty? Forty? Sixty?” Hauk responded. “The…
