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.

Frontiers of Structural and Civil Engineering 2014, Volume 8, Issue 4,   Pages 448-455 doi: 10.1007/s11709-014-0262-x

Abstract: Rock mass classification system is very suitable for various engineering design and stability analysis. classification method is confirmed by Japan Highway Public Corporation that this method can figure out either strength or deformability of rock mass, further appropriating the amount of rock bolts, thickness of shotcrete, and size of pitch of steel ribs just after the blasting procedure. Based on these advantages of method, in this study, according to data of five deep and long tunnels in Iran, two equations for estimating the value of method from and classification systems were developed. These equations as a new method were able to optimize the support system for and classification systems. From classification and its application in these case studies, it is pointed out that the method for the design of support systems in underground working is more reliable than the and classification systems.

Pinghua Tang, Mulin Luo, Ting Zhao, Yuliang Mao,pinghuatang@xtu.edu.cn,1011773923@qq.com,zthaza@126.com,ylmao@xtu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 3,   Pages 287-436 doi: 10.1631/FITEE.2000372

Abstract: We demonstrate the generation of noise-like pulses (NLPs) and soliton rains in a saturable absorber mode-locked erbium-doped fiber laser. Typical NLPs are obtained at a proper pump power and in a cavity polarization state. The soliton rain operation with multiple solitons can be achieved by finely adjusting the cavity polarization state. In addition, distinctive multi-soliton interactions are observed and investigated, including the fundamental mode-locking and multiple pulses. The experimental results can help further understand nonlinear pulse dynamics in ultrafast optics.

With the intelligentization of advanced manufacturing, the laser cutting and joining technology will be surely promoted by the integration of laser technology and digital manufacturing technology. This study selects and analyzes four specific technologies that are most widely used in industry to summarize the application status of the laser joining and cutting technology, namely, laser welding, laser cutting, laser drilling, and laser marking. The problems faced by the development of the laser joining and cutting technology are discussed. The study shows that the development of laser cutting and joining technology should focus on the integration of the fundamental processes and equipment so as to improve key technologies in laser processing unit, laser materials processing, and intelligent integration. Moreover, research platforms for fundamental processes should be strengthened, with a focus on multi-dimensional combination of technological innovation and talent training. This will promote the coordinated development of the laser cutting and joining technology from application development to equipment market guarantee.

Strategic Study of CAE 2020, Volume 22, Issue 3,   Pages 14-20 doi: 10.15302/J-SSCAE-2020.03.003

Abstract:

Laser diagnosis and treatment technology has been successfully applied in the field of healthcare and become an important part of precision diagnosis and treatment in modern medicine. This article focuses on the medical application of laser technology and summarizes the development status, trends, and problems of China’s laser technology in clinical treatment, diagnosis, and industrialization, from the perspectives of practical application and industrial chain. The study revealed that China’s laser medicine has made great progress in terms of laser treatment technology, medical laser diagnosis and treatment equipment, and the industry; however, on the whole, the clinical application of laser medical technology is still catching up with the global trend. The applied research of the technology still lacks original creativity, and the research and industrialization of medical laser equipment are at the mid-low end. The key technologies and high-end equipment such as ultrafast lasers for precision diagnosis and treatment are still under foreign monopoly. The study proposes that China should establish sub-disciplines under laser medicine; strengthen the construction of national science and technology innovation platforms for laser medicine; develop regulations on laser medical equipment in a targeted manner; launch relevant policies to support the development of the laser medical equipment industry; and strive to make breakthroughs in key technology research for medical laser diagnostic equipment.

To promote the development of laser technology and its application, the Chinese Academy of Engineering launched a major consulting project “Strategic Research on China’s Laser Technology and Its Application by 2035” in 2018. This paper is a comprehensive research report on the project. It briefly analyzes laser technology and its instrumental, leading, and disruptive role in scientific research and industrial application, and summarizes the present situation of research and application of laser technology in frontier laser, manufacturing, information and communication, medical treatment, and other fields in China. Several problems that restrict the rapid development of lasers are presented, and the development goals of China’s laser technology and its application by 2035 are conceived. To achieve these goals, China should strengthen the overall planning at the top level to lead the rapid development of laser technology and its application and strengthen basic research to make breakthroughs in major basic problems, common technology foundation, and basic materials and devices. It also should establish research and development special projects concerning laser application to create multiple new laser industry chains, and innovate its industry coordination mechanism to improve the innovation ecology of laser industry. Moreover, China should strengthen the basic education concerning the laser technology and promote talent cultivation of the laser and optical disciplines.
