The interaction of water and light emits laser pointer for the first time

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…

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…

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…

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…
