In these lasers, the laser medium is composed of one or a mixture of gas or vapor. Gas lasers can be classified according to the type of transition that caused their operation: atomic or molecular. The most common of all gas laser pointer is the He-Ne (He-Ne) laser. The presence of two atomic species (helium and neon)…

The development history of laser
In 1917, Albert Einstein laid the foundation of laser pointer technology when predicting the phenomenon of “stimulated emission”, which is the foundation of all lasers. In 1960, Theodore Maiman built the first working laser engraver prototype at the Hughes Research Laboratory in Malibu, California. The laser uses synthetic ruby as the active medium and emits a deep red beam…
Use laser energy to modify the shape or appearance of materials
laser pointer processing uses laser energy to modify the shape or appearance of materials. This material modification method has many advantages, such as the ability to quickly change the design, produce products without copying them, and improve the quality of finished products. Another advantage of laser material processing is its compatibility with multiple materials. Compatible materials…
Interaction between laser energy and material
The influence of the interaction between laser engraver and material largely depends on the wavelength and power level of the laser, as well as the absorption characteristics and chemical composition of the material. The first generation of laser marking machine is the lamp pump YAG laser marking machine. It is large and has low energy transfer efficiency….
High-end laser marking machine
This physical process removes material. The material is completely removed from the top to the bottom surface, or part of the material is removed from the top of the material down from the specified depth. Material ablation is used for laser engravercutting, laser engraving and laser drilling. There are also some new high-end laser marking machines,…
Laser etching products
Whether your next laser etching product is an art product or an industrial product, choosing the best laser pointer machine that can meet your needs is the first step to success. This physical process changes the properties and/or appearance of the material. Material modification is used for laser marking on the material surface by changing the appearance…
The origin of the gas laser pointer
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…
