The HeNe laser was the first continuous wave (cw) laser invented. A few months after Maiman announced the invention of the pulsed ruby laser pointer, Ali Javan and his colleagues W. R. Bennet and D. R. Herriott announced the creation of their continuous helium-neon laser. This gas laser is a four-level laser that uses helium atoms…

Britain plans to develop laser pointer weapons with actual combat capabilities
The British Secretary of Defense Fallon announced that a laser directed energy weapon demonstration project in the UK has entered the final approval stage. The project mainly verifies the feasibility of new laser pointer weapons in order to develop laser weapons with actual combat capabilities in the future. According to the British Ministry of Defense, the contract…
Boeing and General Atomics join forces to develop new laser pointer weapons
The two companies are working together to build a new type of high-energy laser pointer weapon for the US air defense and missile defense system. According to the agreement, the two companies will develop a laser with a power of 100KW, which can be integrated into aircraft, ships and automobiles as an independent device. General Atomics will…
Laser pointer weapons will break the balance of modern defense
In 2017, a U.S. military ally detected an unusual threat: a small quadcopter was approaching. This kind of drone is priced at US$200 online, and everyone can buy it. In the end, the drone was shot down by a Patriot missile worth 3 million. The threat was wiped out, but it was expensive. This incident…

New research is expected to achieve large-scale commercial applications of terahertz laser pointers
Just like those heroes in poor-quality movies and interstellar novels when they first think of weapons when they choose weapons, they are all laser pointer weapons. This kind of device generates coherent electromagnetic radiation beams by stimulating atoms or molecules to excite photons, but the speed of this technology improvement has been It’s a bit outdated. Nowadays,…
This opens up a broad market for laser pointer applications
Laser display is not a new technology, it has a history of 50 years. In the 1960s, the world’s first visible light laser pointer, the ruby laser, was successfully developed by Hughes Laboratories, which opened up a broad market for laser applications; in the 1990s, all solid-state lasers pushed laser display technology into the R&D stage;…
Why is the laser pointer display technology so hot?
In recent years, laser display technology has become the new favorite of projection companies and home appliance companies, including Hisense, Divi Video, Barco, Christie, NEC, Sony, LG, Changhong, Nuts, Guangfeng Optoelectronics, Simeile, Konka, etc. Leaders in the large-screen display industry have also established their presence in this field, and have continuously made breakthroughs, and the laser…
Display technology is combined with monochromatic laser pointer
The RGB pure laser engineering projector using the latest pure semiconductor laser pointer light source adopts the separate design of the laser light source and the projector optical machine, and has the characteristics of ultra-high output brightness, ultra-high resolution, ultra-long service life and extremely high color saturation. At present, the luminous flux output of a single unit…
Analysis of the characteristics of the three mainstream technologies of laser pointer projection
In 1640, a Jesuit priest named Atanas Koscher who was born in Gesha, Germany, invented a slide projector called the “magic” lamp, which was the first projector in the world. After three and a half centuries, EIKI produced the world’s first 16mm film projector in 1953, SHARP launched the world’s first single-chip LCD video projector…
