Recently, the research team of the Aerospace Laser Technology and System Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, reported for the first time a low repetition frequency full polarization maintaining 9-shaped cavity fiber laser at 915 nm. The relevant research results were published in Optics Express under the title "Low repetition rate 915 nm ...
Recently, the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in the research of Nd: ASL (Sr0.7Nd0.05La0.25Mg0.3Al22.7O19) laser crystals, and the related achievements were published in Infrared Physics&Technology under the title of "Tunable laser operations on Nd doped cont...
For example, the commonly used square shell battery cells for power batteries include laser welding of cover explosion-proof valves, laser welding of pole columns, and laser welding of cover plates and shells. During the process of laser welding of aluminum alloy, it is easy to generate unqualified phenomena such as explosion points, pores, welding cracks, excessive depth and width of fusion. ...
In a groundbreaking scientific study published in Volume 13 of the Scientific Report, researchers reported on the results of Young's double slit interference experiment using oscillating vortex radiation under a photon counting system. The experiment involves using a spiral oscillator to emit second harmonic radiation in the ultraviolet range. Using an ultra narrow bandpass filter in the low curre...
