Recently, a research team from the Aerospace Laser Technology and Systems Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, proposed a new holographic imaging technology using frequency domain direct sampling. The relevant results were published in Optics Letters under the title of "Fourier inspired single pixel holography".Digital holography is a tech...
Recently, researchers have developed a comb laser with higher stability and efficiency. The use of synthetic reflection self injection locking micro comb design enables the laser to achieve stability and increase conversion efficiency by more than 15 times. This efficient, stable, and easy to manufacture design is expected to make rapid progress in fields such as portable sensors, autonomous navig...
Superlenses are nano artificial structures that can manipulate light, providing a technique that can significantly reduce the size and thickness of traditional optical components. This technology is particularly effective in the near infrared region, and has great prospects in various applications, such as LiDAR, which is called "the eye of autonomous vehicle", mini UAV and blood vessel detector.D...
Recently, Coherent, an industrial laser technology giant, announced the launch of a new 2D laser cutting head - CUT12, which combines excellent performance, high versatility, and profound value for the global flat cutting market. Image source: CoherentThe CUT12 sheet metal laser cutting processing head is perfectly compatible with fiber lasers in the power range of 4 kW-12 kW (continuous wave),...
The first all-Italian quantum cascade laser was born at the National Research Center in Pisa. The protagonists of this milestone are two researchers from the Nanoscience Institute, Lucia Sorba and Miriam Serena Vitiello, who together with their research team designed and developed this innovative device.In fact, quantum cascade lasers have unique potential for detecting gases and other molecules, ...
