The Bragg mirror is composed of alternating Si02 and Ti02 coatings, and the refractive index of the coating changes stepwise. Such a structure introduces a negative dispersion relationship. The front of the mirror is like a transmission grating that produces partially reflected light, while the back of the mirror produces Bragg reflection. In order to…

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…
Objectively reflect the phase noise of single-frequency fiber laser pointer
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…
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…
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,…
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…
The Large Laser Pointer Turret At The Nose
In addition, on October 17, 1997, a ground-based chemical laser transmitter was used to launch a laser beam to a military weather satellite to be scrapped. This infrared chemical laser, called MIRACL, used a high-power laser to irradiate the Air Force MSTI-3 research satellite in low earth orbit for the first time. The laser beam…
The Advantages of Laser Pointer Application of Light Source in The Display Field
LASER light source is an electric light source that uses excited particles to emit light under the action of stimulated radiation, and is a coherent light source. The concept of laser display appeared in the 1960s, and scientists all over the world tried to apply laser technology to the research of display light sources. However,…
