The US Air Force Research Laboratory established the Air Force’s first high-energy laser weapon system overseas for a 12-month field evaluation. The Office of Strategic Development Planning and Experimentation of the Air Force at Wright Patterson Air Force Base in Ohio is leading the project. Dr. Michael Kyrgyz, Director of Basic Defense Experiments, Office of…

The US Air Force successfully shot down multiple missiles with laser pointer weapons
The US Air Force is getting closer and closer to the target of using laser weapons to equip fighters. Testers at the Baisha Missile Range used the “self-protection high-energy laser demonstrator” to successfully shoot down multiple air-launched missiles. Although it is currently a behemoth on the ground, the final product technology should be portable and…
One of the key technologies is to combine many tiny laser pointers
There are two types of micro lasers: fiber lasers or laser cavities and single-tube semiconductor lasers. The synthesis is carried out in three steps: the first step is to integrate many small fiber lasers into a linear array in parallel to form a “bar”; the second step is to integrate many bars in the horizontal…
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…
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…
Important technology of laser pointer that generates ultrashort pulses
The so-called Q-switching refers to the technology of adjusting the Q value of the laser. In the initial stage of laser pumping, the Q value of the resonator is adjusted to a very low level, so that the laser does not meet the oscillation conditions temporarily. When a high particle number density is obtained under…
What is a single-frequency fiber laser pointer?
Single-frequency fiber laser: It has the advantages of long coherence and narrow linewidth and plays an important role in many special fields. Since the advent of the first ruby laser in 1960, laser technology has undergone many changes, and now it has become a covering industrial processing, communications, medical, military Important technologies in many fields….
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…
Market status and application prospects of single-frequency laser pointer
At present, there are no products with single-frequency semiconductor lasers with a linewidth lower than 1kHz. Because single-frequency fiber lasers have a long cavity length, and the key component-fiber gratings are very sensitive to temperature and vibration, which affects wavelength stability and frequency The control of drift is a challenge. It is reported that the…
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…
