	Yongkang Dong, Harbin Institute of Technology, China Title: Ultra-fast distributed Brillouin optical fiber sensing for dynamic strain measurement Abstract: In this paper, some latest methods of dynamic measurement based on fast BOTDA are summarized and analyzed, including polarization compensation technique, frequency-agile technique, slope-assisted method, optical chirp chain technique, optical frequency comb technique.
	Corin Gawith, University of Southampton, UK Title: Diced ridge waveguides in MgO: PPLN for applications in quantum technology space applications of cold atoms Abstract: Periodically Poled Lithium Niobate (PPLN) enables off-the-shelf lasers to be converted to specific wavelengths for light-matter interactions in atom/ion traps. We introduce a rugged Zn-indifused MgO:PPLN diced ridge waveguide format enabling Watt-level 780nm SHG at 70% conversion efficiency for use in quantum systems.
	Miguel Gonzalez Herraez, University of Alcala, Spain Title: Photonic seismology Abstract: We review our recent work on chirped-pulse distributed acoustic sensing for the characterization of teleseisms and microseisms. We show that this tool may unleash tremendous new capabilities in the field of seismology.

	Minglie Hu, Tianjin University, China Title: Manipulation pulse dynamics in a few cycle pulse fiber laser Abstract: A short introduction for the mode-locking and a brief review of recent work on high power femtosecond fiber laser are demonstrated, which shows that few cycle laser pulse can be obtained by optimization of nonlinear process in fiber laser system.
	Jacob Khurgin, Johns Hopkins University, USA Title: Linear and nonlinear epsilon near zero materials - what is so special about them? Abstract: In this talk I describe the linear and nonlinear optical properties of the “epsilon-near-zero” materials using example of transparent conductive materials like ITO. I show that most of “unusual” properties of these materials can be related to slow group velocity and then I identify the conduction band nonparabolicity as the dominant cause of nonlinearity in them
	Zhaojun Liu, Shandong University, China Title: Preparation and application of Yb:YAG crystal derived silica fibers Abstract: Yb: YAG-derived silica fiber (YDSF) was fabricated by using molten-core method. Through this fiber, a single-frequency 1064 nm laser was realized. The output power was 110 mW with a linewidth of 93 kHz.
	Fufei Pang, Shanghai University, China Title: Optical fiber sensors based on vortex or vector modes Abstract: Vortex beams and vector beams have helical phase front and non-uniform polarization state, respectively. Vortex fiber with a ring core can guide the vortex and vector modes stably. Based on the vortex or vector modes, we have investigated the sensing properties of the vortex fiber for magnetic field and strain.
