In actual cleaning, the filling interval should be reasonably determined according to the size of the cleaning spot to avoid unevenness of the shading after cleaning. From the essence of the coupling effect of the green laser pointer and the material, factors that may affect the efficiency and effectiveness of rust cleaning are: Power density (energy density),…

Analysis Of Process Influencing Factors Green Laser Pointer
In view of the above green laser pointer cleaning machine, the pulse width, pulse waveform and light intensity distribution have been fixed, so the experimental test is mainly carried out in terms of power density (energy density), spot size, and spot overlap rate, and how various factors affect the pulsed laser The cleaning efficiency and cleaning effect…
Diffraction Laser Aperture Extends Shelf Life Of Green Laser Pointer
It is reported that the German green laser pointer and the components and services manufacturers of the optoelectronic industry said recently that the micro-holes generated by the laser help maintain the freshness of packaging products. These apertures are constructed using a diffractive optical element (DOE); an optical device that converts a single laser beam into multiple small…
Scientist Laser Pulse Green Laser Pointer
“From the perspective of missile range, there is no problem with altitudes of 200, 300 kilometers and even higher. At present, human beings can send satellites weighing several tons to orbits of 36,000 kilometers.” Song Baohua said, but there are some difficulties in accurately targeting asteroids. . He said that for spacecraft made of metal…
A Nuclear Bomb Explosion Destroys Asteroids Green Laser Pointer
An experiment by Russian scientists these days has attracted a lot of attention. They used green laser pointer pulses to simulate a nuclear bomb explosion to destroy a meteorite model to understand what kind of explosive force is needed to destroy an asteroid. The asteroid hitting the earth is undoubtedly a nightmare that makes humans think terribly….
Important Application Potential Green Laser Pointer
Talking about how to publish a high-level paper, Qu Songnan humbly stated that there are not too many skills in this regard. The first is that the research direction must be valuable and promising, and the second is that the research content must be the core problem in the field and the current The main…
Infrared Fluorescence Imaging Green Laser Pointer Application
Existing absorption and emission bands of carbon nanodots are mainly located in the ultraviolet-visible region. High-efficiency absorption in the near-infrared region and high fluorescence quantum efficiency near-infrared luminescence cannot be achieved, which severely limits carbon nanodots in biofluorescence imaging, especially green laser pointer application in in vivo near-infrared fluorescence imaging. In recent years, in order to solve…
Break Through Technical Bottlenecks Green Laser Pointer
It is reported that the study of carbon nanoparticle’s luminescence mechanism and spectrum regulation are the difficult points in this field. Before 2013, the emission of carbon nanoparticles in the green light band was thought to originate from the surface defects of carbon nanoparticles, and this green laser pointer light source was considered to be difficult to…
Promising To Change The Future Lighting World Green Laser Pointer
In 2006, scientists at the University of Clermontson in the United States produced a type of carbon nanoparticle that emits bright light when illuminated. Scientists also found that green carbon pointers with luminescent carbon nanoparticles have unique advantages, such as chemical stability, no light flicker, light drift resistance, non-toxicity, cheaper manufacturing cost, and excellent biocompatibility….
New Laser Material Green Laser Pointer
Recently, Qu Songnan’s research group at the Changchun Institute of Optics and Mechanics of the Chinese Academy of Sciences broke through the problem of low luminous efficiency of carbon nanodots in the near-infrared band. For the first time, they developed carbon nanodots with highly efficient near-infrared absorption / luminescence characteristics, and realized a green laser pointer….
