Scientists at the University of Vienna succeeded in encrypting the bending laser beam and allowed the bending laser pointer beam to travel up to 143 kilometers. This travel record set a new world record, almost 50 times higher than the previous record. This new breakthrough may bring revolutionary changes to satellite communication methods. Light is an electromagnetic…

The circular laser pointer beam has a spiral phase distribution
A micro-nano structure similar to the thorns on the surface of a cactus is produced by three-dimensional light curing. The micro-nano structure can simulate the hydrophobic characteristics. These micro-nano structures have great application value in the field of biomimetic materials. But if we look closely, the detailed structure is actually layered. In our 3D printing…
Laser energy-saving gun can directly output Chinese characters
This part is the result of new scientific research released last year and this year. In addition to the states on the previous page, this mode will also have more complex laser modes, which are actually different Hermitian Gaussian beams and Laguerre The complex superposition of Gaussian beams. On the left is the superposition state…
Some optical components that regulate the laser pointer
Then, like the curve on the right like a positive rotating wave, in fact, one cycle of the laser field itself oscillates in the cavity is a laser pointer wavelength, so there may be many laser wavelength values in the cavity. Then this is called the longitudinal mode of the laser, because it is along the cavity…
The spatial structure of the interactive forming laser pointer
These applications in various aspects, this is a simple example. We are laser additive manufacturing, here is also the meaning of it. In our additive manufacturing or laser pointer-based additive manufacturing, we first build a two-dimensional structure, and then continue from two-dimensional to three-dimensional process. In fact, this process can be referred to as laser 3D…
Will the new laser pointer mode trigger changes in 3D printing technology?
As the energy form of melting powder materials in 3D printing technology, lasers occupy a core position in different fields such as metals and polymers. The general laser pointer mode is a point; however, if there is a brand-new laser mode, will it trigger a new 3D printing technology revolution? The first point: It is possible that…
Replace people with machines to improve production efficiency and introduce laser pointer technology
Metal 3D printing has now become a high-profile focus of the entire 3D printing industry. For a long time, metal 3D printing technology has been considered not mature enough because this technology faces limitations in materials, speed and construction volume. Today, these restrictions are improving step by step. Recently, Adira (Portuguese machine tool manufacturer) announced…
The results of the research team in the new laser pointer mode
After this, it was only in 2017 that they continued their work. In fact, their work was very similar. They also used the first-order Laguerre Gaussian beam to produce the same cone-shaped micro-nano structure, but their The structure is richer, they analyzed more parameters and more situations, and produced different results. The next job was…
Test laser pointer to realize laser communication
“80 satellites carrying IoT communications will be launched by 2023 to achieve global coverage.” On the 24th, the fourth “China Space Day” series of events were held at Wuhan National Aerospace Industry Base, Deputy General Manager of Aerospace Cloud Technology Co., Ltd. Du Li said that Xingyun Project will launch two test satellites, Xingyun II…
Vision Correction Surgery Laser Pointer Promotes British Vision Storm
Due to technological breakthroughs, scientists have managed to make laser eye surgery more effective and cheaper than ever. Any glasses wearer will tell you that glasses are hardly a practical choice. You may break or lose them at any time. They are a nightmare, especially when you walk on the street on a rainy day…
