DFB laser chip (distributed feedback laser chip) is a key device for the integration of three networks (telecommunications network, radio and television network, Internet), cloud computing data center, and 4G / 5G wireless communication network. The manufacturing process is very complicated. At present, DFB laser chip manufacturing technology is mainly in the hands of developed…

A Gorgeous Picture Of The Laser Pointer
From a technical point of view, the currently popular monochromatic laser pointer light source on the market uses a blue laser as the core, cooperates with a fluorescent pink wheel to form white light, and then uses the color wheel to separate colors. The biggest disadvantage of this method is that the red and green colors are…
Three-color Laser Extreme Color Experience Laser Pointer
Since it is a grand event for the display industry, many manufacturers in the projection industry will not be absent. After years of accumulation and precipitation, laser light sources have been widely recognized by major industries. Therefore, from 8K laser to tri-color light source, laser pointer has become a well-deserved protagonist of the projection industry…
Bring A Total Solution Laser Pointer
Projectors are mainly divided into three major areas: business education, engineering and home. Among them, engineering projection has the highest requirements for brightness, so a bright laser has a unique advantage in this field. In addition, with the emergence of HLD in education, the advantages of laser projection have become less obvious. Therefore, many manufacturers…
Accurate Detection Of Air Pollution Laser Pointer Radar
“As long as the lidar is turned on, you can see the distribution of pollution sources.” On April 10, in a CMB car in the courtyard of the Shijiazhuang City Environmental Prediction and Forecasting Center, the staff turned on the laser pointer radar device and approached The three-dimensional distribution of pollution within 15 kilometers from the ground…
Remove These Bombs Safely Laser Pointer
For the safety of citizens around the world, unexploded bombs remain a significant threat. In order to be able to remove these bombs more safely in the future, the Hannover Laser Center in Germany is working with local German companies to jointly develop bomb pointer-based bomb removal methods. The traditional methods of removing bombs face…
Developed 3D Printed High-temperature Polymer Laser Pointer
When testing high-temperature polymer resins, the research team found that additive manufacturing technology printed polymer powders well, but when they removed the parts from the powder bed for post-processing, the materials melted and became unusable. To solve this problem and better entangle and shape the molecules under the heat of the laser, the researchers added…
Military Uses Selected Laser Pointer Sintering Process
Recently, the United States Air Force Research Laboratory, in collaboration with NASA’s Glenn Research Center and the University of Louisville, has developed a method for 3D printing high-temperature polymers. Researchers have used high temperature thermosetting resin impregnated with carbon fiber filaments and selected laser sintered laser pointer processes to successfully print high temperature resistant polymer-based composite parts…
Observe The Riding Status Of The Cyclist Laser Pointer
Google software already recognizes many cyclists’ gestures when they want to turn. The laser pointer system can also observe the rider’s riding status and predict what they might do next. Google says its self-driving cars can even “remember” the cyclist’s hand movements as they move away from the intersection to better predict whether the cyclist will then…
Able To Recognize The Intention Of The Cyclist Laser Pointer
The general cruise laser pointer assist function will require the driver to hold the steering wheel tightly all the time, but this universal cruise mode with facial recognition will allow the driver to leave the steering wheel with both hands. However, once it is detected that the driver is distracted or even falling asleep during driving, this…
