The huge spaceborne laser pointer weapon is technically difficult
There is no air in space, and SBL does not have the problems of beam refraction, absorption, jitter and thermal blooming in the atmosphere. However, the biggest problem with space laser pointer weapons is sufficient power, and the technical difficulty of deploying massive and bulky spaceborne laser weapons in orbit is too high. , Reliable, controllable, high…
Laser weapons change air combat each shot costs $1 and can be fired continuously
It is said that the theoretical basis of laser was established by Einstein in 1917, but it was not until 1957 that people really discovered laser pointer. Laser has the characteristics of good directionality, concentrated beam, good monochromaticity, and powerful power. It does not require much imagination to see the potential of laser as a weapon….
Physicists photographed crystal structure transformation under laser beam
Laser beams can be used to change the properties of materials in extremely precise ways. This principle has been widely used in technologies such as rewritable DVDs. However, the basic process is generally carried out at such an unimaginable speed and such a small scale that it has not been directly observed so far. Researchers…
China’s synthetic aperture lidar achieves new progress
There are stories about “clairvoyance” in Chinese mythology, but the eyes of all creatures in nature cannot see the distance of a thousand miles. The development of new technologies, especially the development of synthetic aperture lidar (SAL) technology, may really enable humans to have “clairvoyance” capabilities. It is a high-resolution imaging lidar. Its outstanding feature…
Absorb light from the wavelength and convert it into a different laser pointer wavelength
The test has two advantages. The first one is: In principle, it happens often, which is also certain. The second is that the photon is not lost, but just transferred, so it can be used for other purposes. This scheme uses a single fixed rubidium atom, which is cooled to near absolute zero by a laser…
Extract a single light particle from the laser beam
The researchers said that extracting a single light particle from a laser pointer beam may bring a huge breakthrough in quantum computing. Physicists from the Weizmann Institute of Science in Israel successfully extracted a single photon from a single beam of light using ultra-cold atoms and cutting-edge optical technology. Physicists are very interested in individual photons because…
Laser experiments reveal that the moon has a fluid core
What information can scientists gather from the laser pointer light reflected from the lunar reconnaissance orbiter? First, it accurately reveals the time it takes for the photon to go back and forth-2.5 seconds on average. Scientists can use this time to determine the exact distance of an object. At the same time, by measuring tiny fluctuations in…
Scientists look for laser pulses carrying this civilization signal around strange stars
According to media reports, scientists discovered a strange light curve on the KIC8462852 star, suggesting that there may be an alien civilization here. A huge structure appeared near the KIC8462852 star. To help rule out this possibility, scientists searched for all the signals around the star, one of which was a very short laser pointer pulse. If…
Global semiconductor laser market outlook and growth analysis
According to relevant data, the global semiconductor laser pointer market will exceed 7.69 billion U.S. dollars by 2020, with a compound growth rate of 7.1% from 2014 to 2020. Semiconductor lasers have been widely used in many fields, including sensors, optical storage devices, health care, industrial machinery manufacturing, communications, lithography, and national defense. Among them, communication applications…
