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, ...
The team of Wu Dong, professor of the Micro/Nano Engineering Laboratory of University of Science and Technology of China, proposed a processing strategy of femtosecond laser two in one writing into multiple materials, manufactured a micromechanical joint composed of temperature sensitive hydrogel and metal nanoparticles, and then developed a multi joint humanoid micromachine with multiple deformat...
The 3500W free output blue semiconductor laser beam is output in a free space manner, with a rectangular spot directly acting on the material surface without the need for fiber optics or laser processing heads. This laser has a wavelength of 455 ± 10nm, with continuously adjustable power and a maximum output power of over 3500W. It is mainly used for non-ferrous metal cladding, quenching, etc., to...
Researchers from the Hanover Laser Center and Leibniz University in Germany reported on the mechanism of increased welding depth during time power modulation in high-power laser beam welding. The related paper titled "Mechanisms of Increasing Welding Depth during Temporary Power Modulation in High Power Laser Beam Welding" was published in Advanced Engineering Materials.Understanding the basic mec...
The Light Detection and Ranging (LiDAR) market embodies the technology of remote sensing, surveying, and the use of laser pulses to measure distance and generate detailed three-dimensional models of objects, terrain, and environment.The LiDAR system emits a laser beam and measures the time required for the light to return to the surface, creating accurate and high-resolution digital representation...
