Its core technology is to write phase-shift fiber gratings inside the active fiber core doped with rare earths. There is a certain distance between two segments of uniform-period fiber Bragg gratings to achieve a specific phase shift, such as 1/4 wavelength. Or 1/2 wavelength. Through the excitation of pump light, the output of single frequency laser…

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…
China is Developing Anti-drone Technology And Laser Pointer Weapons
The Hong Kong “South China Morning Post” website published a report entitled “China is developing anti-UAV technology and laser weapons at full speed, trying to catch up with the United States.” According to military analysts, China is taking actions to develop laser weapons and anti-UAV systems in an attempt to catch up with the United…
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…
Turkey Develops Two Continuous Wave anti-drone Laser pointer Weapons
The Turkish Communication Security Research Center has completed the development and testing of two laser pointer systems and plans to equip the Turkish Army. It is understood that both laser systems use continuous wave lasers with a working wavelength of 1070 nanometers (±10 nanometers). The first type of laser system is called a vehicle-mounted laser system, which…
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…
The World’s First Water Wave Laser Pointer
Technical researchers have demonstrated for the first time that laser emission can be produced by the interaction of light and water waves. This “water wave laser” may one day be used on tiny sensors that combine light, sound and water waves, or as a microfluidic “lab on a chip” for studying cell biology and testing…
The Leap from High-end Equipment to Large-scale Laser Pointer Applications
As we all know, in the field of mechanical engineering and civil engineering, there are always various problems and challenges in the measurement of vibration characteristics. Although some vibration originates from the device or component itself, abnormal vibration caused by external forces or design tolerances can cause functional damage to the device or component. Therefore,…
