Laser technology startup Enlightra collaborates with DESY Hamburg to develop and design more stable and efficient comb lasers. This work demonstrates a microresonator with programmable synthetic reflection, providing tailored injection feedback for driving lasers. This technology has significantly improved compared to traditional self injection locking technology and can be produced using standard...
The beam emitted by almost all laser systems follows the Angle pattern of Gaussian distribution. The Gaussian irradiance distribution means that irradiance has a smooth peak at the center point and slowly declines toward the edge. In theory, the irradiance level of a Gaussian distribution can never reach zero, which means that the distribution can expand indefinitely. This phenomenon in the laser ...
Recently, in order to improve the National Aeronautics and Space Administration (NASA) space communications capabilities, NASA plans to send a technology demonstration called "Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T)" to the space station in 2023.ILLUMA-T and the Laser Communications Relay Demonstration (LCRD), launched in December 2021, will together comp...
Recently, researchers at the Rensselaer Polytechnic Institute in the United States have invented a miniature device thinner than human hair, which can help scientists explore the essence of light and matter and unravel the mysteries of the quantum field. The most important advantage of this technology is that it can work at room temperature without the need for complex infrastructure. The resea...
Recently, the team led by Wang Rui from the Future Industry Research Center and the School of Engineering at Xihu University has made significant breakthroughs in the field of flexible stacked solar cells. They have successfully stacked perovskite and copper indium gallium selenide materials together, resulting in a photoelectric conversion efficiency of 23.4%. The related research paper was recen...
