Recently, Yang Shanglu, a researcher at the Laser Intelligent Manufacturing Technology Research and Development Center of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made new progress in laser welding of the fourth-generation reactor-molten salt reactor structural material Ni-28W-6Cr nickel-based superalloy.The research team applied the high power fiber ...
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...
