In the mark printing industry, green laser pointer marking has the following characteristics: 1. Permanent; if the mark does not fade due to environmental concerns (touch, acid and alkaline gases, high temperature, low temperature, etc.). 2. Anti-counterfeiting; the marks carved with laser marking technology are not easy to imitate and change, and have a strong anti-counterfeiting to…

Non-contact permanent marking of fiber laser marking machine. The green laser pointer mark is a method of marking a visible pattern by using a high-energy-density laser beam to cause a physical or chemical change on the surface of the target. The strong and permanent mark produced by the laser on the workpiece surface is its prominent Features….

The team successfully demonstrated this green laser pointer for U.S. advanced intelligence research project activities in August 2017, analyzing 70 mysterious samples in a two-day test. The second phase of the project will require the system to be reduced to the size of a shoebox. This process will be initiated and led by the world’s leading technology…

This is the magic of the device. We injected pulses of about 1 nanosecond with such a high power green laser pointer, and then they broke down into a very narrow series of short pulses, usually less than 1 picosecond wide. In this way, the equivalent output of an expensive mode-locked laser is obtained with a…

Germany is also building a “network army” with both offense and defense. In April this year, the German Federal Defense Forces established the Cyber ​​Information Space Command and set out to set up an independent service of the green laser pointer Defense Forces responsible for network security. It is envisaged that this force will have both cyber…

“The characteristics of these storage methods are different. Specifically, the laser pointer hard disk storage can achieve fast recording and reading of data and meet the needs of fast online access to data. It is the current mainstream storage method. Its fast reading and writing speed can Quickly perform data storage, query, and retrieval operations, and the…

Persistent storage ‘is just a theoretical laser pointer concept. In fact, under specific storage conditions, the existing optical storage technology can theoretically achieve ‘permanent storage’. However, research on optical storage technology focuses on the storage of actual data. In addition to the technology itself, many factors such as cost, implementation, and market promotion must be considered. Scientists…

Taking China Group as an example, it has built a single 300GB optical disc production line in Dalian. The use of optical disc cartridge packaging technology can make a single optical disc cartridge the same size as a single hard disk with a storage capacity of 3.6TB. And multi-layer technology to achieve single-disk TB and…

The data shows that the system has completed the ground wind tunnel test, which includes the use of a ground-based laser pointer charging system in the wind tunnel, which is a “stalker” hand-throwing single-person drone (the type of machine is the “skunk factory “It was specially developed for US Special Operations Command. It entered service in 2006,…

Launch of hybrid silicon-based laser. This laser pointer laser is based on the existing silicon-based waveguide chip, and directly bonds the mature III-V semiconductor laser, so that the two components are combined into a hybrid silicon-based laser. Similarly, silicon itself is not a light source. Hybrid lasers have poor compatibility with existing silicon processes and can cause…
