The Technion-Israel Institute of Technology issued an announcement on the 29th, stating that for the first time, researchers at the university have proved through experiments that the interaction of water and light can also emit laser light, building a “bridge” between two research fields that were previously considered unrelated. The new “water-wave laser” can be…

Explain in detail the development history and key technologies of ultra-fast laser pointer
In 1960, the first laser, the ruby laser, opened the door for the study of ultrafast processes. In 1961, Q-switching technology realized the first short laser pulse output with a pulse width of tens of nanoseconds on a ruby laser. The pulse width of the laser pulse was even shortened to 10 nanoseconds. The pulse…
Four key performance indicators of single-frequency laser pointer
Due to the narrow line width and low noise of the single-frequency laser, it means that it is more sensitive to high-precision vibration, and the long coherence length ensures the accuracy of long-distance sensing. Therefore, the single-frequency laser has high precision/high sensitivity/long distance Sensing systems, next-generation communication technology, coherent technology, remote sensing technology, coherent lidar…
Single-frequency fiber laser pointer relaxation oscillation peak
Compared with semiconductor lasers, single-frequency fiber lasers have a much longer resonant cavity. Take the distributed feedback (DFB) single-frequency fiber laser pointer with a short straight cavity structure as an example. The resonant cavity length is about 2-10cm, while the single-frequency semiconductor The resonant cavity of the laser is on the order of hundreds of um to…
Star Wars Drone Laser Pointer Comes Out to Launch Laser
If you grew up with “Star Wars”, you may dream of becoming a pilot and flying a fighter plane to fight in space. The company is ready to help us fulfill our dreams, and it launched the Star Wars drone. The full name of the drone is called, first listed in the UK, and now…
5kW Laser Pointer Weapon System Destroyed Hundreds of Drones During Testing
According to US media reports, Boeing, the world’s largest aerospace company, recently announced that its Compact laser pointer Weapon System (CLWS) has recently completed a series of key demonstrations in cooperation with the US Air Force and Army. The latest news shows that the CLWS weapon with a power of 5 kilowatts has successfully completed several combat…
Israel Develops Light Blade Laser System to Respond to Aerial Threats Such as Drones
At present, the UAV laser pointer still needs to maintain communication with the operator or GPS. Therefore, the electronic jamming system can use this weakness to implement “soft kill” against the UAV threat, that is, eliminate the UAV’s operating state through hacking technology. However, future drones will navigate through on-board sensors and cameras, avoiding any…
Analysis on the Application of Adjustable Laser Pointer in Optical Communication
The network application of tunable laser can be divided into two parts: static application and dynamic application. In static applications, the wavelength of the tunable laser pointer is set during use and does not change with time. The most common static application is used as a substitute for source lasers, that is, used in dense wavelength division…
Using Standard Laser Vibration Sensor
The integrated laser vibration sensor module can be applied to large-scale industrial production lines in the form of a standard sensor module on a low-cost basis. Figure 4 shows a typical sensor design. The miniaturized module is equipped with a fixed or manually adjustable lens. All the measured raw data are directly processed in the…
Analysis of China’s Laser Pointer Cutting Industry Chain
Laser processing (including laser cutting, welding and surface treatment, etc.) is an advanced production technology. China’s laser processing industry is making great strides forward. The high-tech term laser has become a real social productivity. “Developing high technology and realizing industrialization” has become a reality in China’s laser processing industry. As a new type of light…
