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…
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…

Mankind’s persistent pursuit of laser precision measurement
With the needs of social development, the requirements for clock laser pointer accuracy are getting higher and higher, so the quartz clock came into being, it is timed by the stable quartz oscillator inside the quartz clock. With the requirements of scientific and technological development and the persistent pursuit of precision measurement by human beings, quartz clocks…
Laser pushes atomic clocks a step further
The origin and extinction of all matter in the universe, the creation and end of all things in the world, the birth and extinction of all life on earth, all of which are closely related to time. The sun and the moon change, the stars shift, and flowers bloom and fall. Thousands of years of…
Blu-ray laser pointer perfectly adapts to application scenarios
Industrial application: Innovate the processing of high-reverse materials, with outstanding advantages in new energy batteries and 3C Although the blue laser pointer is a rookie in the field of laser development, it has obvious advantages in the field of high-reflection material processing. At present, it has gradually emerged in the fields of new energy battery welding, 3C…
The blue laser is generally a semiconductor laser pointer
With the emergence of 10,000-watt fiber lasers in the market, the homogeneity competition has gradually brought the increase of product power to the ceiling, and the vertical high-power stacking route has become more and more difficult. Therefore, more manufacturers have turned to seek lateral breakthroughs in new laser pointer. Among the many breaking directions, the “blue…
The laser pointer market is brewing a new storm

Graphical process laser pointer in micro-nano processing
The patterning process of micro-nano processing is mainly divided into two technologies: pattern transfer and direct processing. The pattern transfer technology includes three parts: thin film deposition, pattern imaging, and pattern transfer. The direct processing laser pointer beam etching technology has the ability to write directly, avoiding the multi-step process of pattern transfer, by controlling the focused…
