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…
The shortest pulse laser pointer that can be obtained under the experimental conditions
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…
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…
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,…
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,…
Analysis of Laser Pointer Reflow Soldering Technology
The perfect spot solder paste system can use various technical methods to complete the soldering of solder joints according to the heating requirements of different products. Similar to other heating methods, misuse of laser energy can easily burn parts. The laser heater makes full use of the characteristics of laser energy transmission and absorption, and…
Small Size Laser Pointer Radar Sensor Will Benefit More Industries
At the same time, two startup companies are working on a vehicle-mounted lidar system that costs $100. They all said they will release products in 2018. Innoviz of Israel promised that its “high-definition solid-state lidar” will have higher accuracy and a larger field of view than similar products in the existing market. Innoluce of the…
