Effects on Residual Stress of Electron Beam Welding of TC4 Al loy by Laser Phase Transformation Treatment

Lu Jinzhong,Zhang Yongkang,Kong Dejun,Ren Xudong,Zou Shikun,Wang Xichang

Strategic Study of CAE 2007, Volume 9, Issue 5,   Pages 72-76

Abstract:

  In this study,  an effective control method and strategy based on fuzzy neural network has been developed for gas injection pressure accurate control in gas-assisted injection. A fuzzy neural network controller with five layers and its control algorithm are established.  The learning ability of neural network is used to optimize the rules of the fuzzy logic so as to improve the adaptability of system.  The simulation of the system capability and three segmental injected pressure control are carried out under the environment of MATLAB and the results show that this theoretic model is feasible, and the control system has good characteristics and control action.

Passive mode-locked Er-doped fiber laser pulse generation based on titanium disulfide saturable absorber Research Articles

Xinxin Shang, Linguang Guo, Huanian Zhang, Dengwang Li, Qingyang Yue,huanian_zhang@163.com,qingyangyue@sdnu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 5,   Pages 615-766 doi: 10.1631/FITEE.2000341

Abstract: In this study, (TiS) polyvinyl alcohol (PVA) film-type (SA) is synthesized with a modulation depth of 5.08% and a saturable intensity of 10.62 MW/cm by liquid-phase exfoliation and spin-coating methods. Since TiS-based SA has a strong nonlinear saturable absorption property, two types of optical soliton were observed in a mode-locked Er-doped . When the pump power was raised to 67.3 mW, a conventional mode-locked pulse train with a repetition rate of 1.716 MHz and a pulse width of 6.57 ps was generated, and the output spectrum centered at 1556.98 nm and 0.466 nm spectral width with obvious Kelly sidebands was obtained. Another type of mode-locked pulse train with the maximum output power of 3.92 mW and pulse energy of 2.28 nJ at the pump power of 517.2 mW was achieved when the polarization controllers were adjusted. Since TiS-based SA has excellent nonlinear saturable absorption characteristics, broad applications in ultrafast photonic are expected.
