The pump source, gain material, and resonant cavity are the three elements that make up a laser. Due to the selective effect of the resonant cavity on the lasing frequency, multi longitudinal mode operation is one of the characteristics of fiber lasers based on traditional resonant cavity structures, manifested as periodic beat peaks in the radio frequency (RF) spectrum and periodic fluctuations i...
Recently, a research team from the University of California, Santa Barbara has successfully developed a new type of photonic memory computing device that integrates non reciprocal magneto-optical technology. This device achieves high-speed, high-energy efficiency, and ultra-high durability photon computing by utilizing the non reciprocal phase shift phenomenon. The research findings, titled "Integ...
According to scientists at MIT, mathematical formulas developed by MIT researchers and other institutions can significantly improve the sustainability of 3D printing.Issues with 3D printing of plastics3D printers typically use mass-produced polymer powders to print parts, which are consistent and predictable, but also difficult to recycle.Other more environmentally friendly options also exist and ...
Recently, the team led by Professor Li Zhiyuan from South China University of Technology has successfully developed a full spectrum white light laser, which has the characteristics of bright spot, smooth and flat spectrum, and large pulse energy. It can cover the ultraviolet visible infrared full spectrum of 300-5000nm, with a single pulse energy of 0.54mJ.The launch of such a full spectrum white ...
