Mei Xin Sheng: The development of high-precision polarized light crown products has been completed

The chip based device, known as the frequency comb, measures the frequency of light waves with unparalleled accuracy, completely changing timing, detection of exoplanets, and high-speed optical communication.Now, scientists and collaborators from the National Institute of Standards and Technology in the United States have developed a new method for manufacturing combs, which is expected to improve...

When scientists discovered that laser pulses can rapidly cause refractive index changes in the medium, resulting in "photonic time crystals (PTC)" in the near-visible light band, the door to a disruptive new application in optics seemed to quietly open.Scientists have a certain degree of understanding of photonic crystals and time crystals, the two have almost nothing in common, the basic common p...

Researchers at the University of Rochester have created new micro comb lasers that go beyond previous limitations and have simple designs suitable for various applications. The research results are published in Nature Communications.Optical frequency combs are optical measurement instruments that have revolutionized atomic clocks, spectroscopy, metrology, and other fields. However, the difficulty ...

Lithium batteries are highly favored in the fields of 3C digital and new energy vehicles due to their high energy density, environmental characteristics, and fast charging and discharging. Welding, as a crucial link in the manufacturing process of lithium batteries, has a decisive impact on battery performance and quality. Laser welding technology is increasingly playing an important role in the l...

German laser Fusion developer Marvel Fusion said it will partner with Colorado State University (CSU) on a new $150 million laser equipment lab to study inertial fusion energy and high energy density physics."It will be home to one of the most powerful laser facilities in the world and an international center for laser fusion energy and high energy density physics research," the company said in a ...
