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…

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…
