Through the MOABB project, DARPA researchers are committed to building a planar millimeter-level transmitter/receiver unit with high fill factor aperture, non-mechanical beam control, and integrated amplification. DARPA scientists claim that free-space optical systems have great potential in sensing, lighting, and communication. Micron wavelengths can achieve an angular resolution of 0.001 degrees. The MOABB project attempts…

Air Force develops chip-level lidar sensor for 3D mapping
According to reports, researchers from the California-based company are developing chip-level, lightweight, economical LiDAR (LiDAR) sensors for military 3D laser pointer mapping, vegetation penetration photoelectric sensing, navigation and long-range communications. Officials of the US Air Force Research Laboratory at Wright-Patterson Air Force Base in Ohio recently announced a $8.2 million contract with the company to develop chip-level…
Japan developed two RGB laser light sources the brightest and the smallest in the world
As part of the NEDO project, Osaka University and Shimadzu Corporation developed two new RGB laser pointer light source modules, mainly using RGB visible light laser diode technology. One of the laser modules has the highest brightness in the world and can be used for high-brightness laser display equipment and laser illumination. Another laser module has the…
Ultrafast lasers for chemical and physical processing of graphene
Ultrafast lasers (picoseconds and femtoseconds) are widely used in thin film patterning in the development and manufacturing of micro-nanoelectronic devices including photovoltaics, displays, sensors, or large organic electronic devices. The main advantage of the ultrafast laser pointer is its limited thermal effect and fast energy dissipation, so as to realize the patterning of complex multi-layer ultra-thin films….
Laser light source has obvious advantages
No laser, no projection, the sound of laser light source in the projection industry is getting louder and louder, especially the laser pointer light source dominates various exhibitions, becoming a good story that every projection brand wants to tell. The laser light source is not rootless grass, and now the swaying posture is also due to the…
Ultrafast pulse lasers increase data transmission speed
According to a recent report by the “Physicists Organization Network”, the ultrafast pulsed laser pointer developed by the Korea Institute of Science and Technology (KIST) produces a frequency 10,000 times higher than the current state-of-the-art pulsed laser. This is achieved by inserting an additional resonator containing graphene into a fiber pulse laser oscillator operating in the femtosecond…
The rapid development of laser light source technology in the Chinese market
The advantages of laser are not only technical, but also have strategic significance for the development of the country’s entire imaging industry. The development of laser pointer light source technology in the Chinese market is very fast, and the gap between technology and foreign countries is not particularly large. In the past, projection light sources have been…
Competition in the laser pointer market will be fierce in the future
In the business and education markets, because the current cost of laser pointer light sources is still too high, it is still difficult for ordinary purchasing agencies to accept the price of tens of thousands of yuan. Therefore, traditional lamp projectors still occupy the main market share. As the cost of laser light sources decreases, I believe…
The maturity of technology allows laser pointer light source projectors to be applied
Laser projectors can be used in areas such as smart cities. Laser light projectors have broad application prospects in the realization of smart cities, safe cities, smart education, smart homes and many other fields. As the country pays more and more attention to green development and supports entrepreneurship, the laser pointer projection industry has an unprecedented opportunity….
The most widely used laser pointer photochemical treatment in laser processing
For single-layer suspended graphene, this value of visible light can be accurate to 2.3%. In addition, the graphene on the substrate can provide up to 10 times the light absorption according to the nature and interface of the substrate. When using an ultrafast laser pointer with a very high photon density, light absorption can be further improved….
