Title: Transverse mode switchable fiber laser based on a beam shaper

Abstract: Two kinds of fiber lasers with all-fiber beam shaper based on single-mode-graded index multimode-few-mode fiber (SMF-GIMF-FMF) structure are proposed. The excitation coefficients of mode can be adjusted continuously by changing the GIMF length. Numerical simulations are performed to investigate beam shaping dynamics in the fiber structure. Switchable output between fundamental transverse mode (LP01) and high order transverse mode (LP11) can be generated. Cylindrical vector beams with high mode purity are also showed by removing the degeneracy of the LP11 mode.

Title: Research on ultra-high sensitivity and ultra-long distance Laser Feedback Interference Technology

Abstract: Compared with the traditional heterodyne interference scheme, the laser feedback interferometry based on the cavity-gain effect has the considerable remarkable advantages of simple structure and not limited by the coherence length of the laser itself, which is an important way and effective means to achieve high-sensitivity measurement of the multiple physical quantities including vibration, displacement, velocity, etc. It is expected to meet the common needs of real-time acquisition of the multi-physical sensing signal in the fields of the measurement of deep-sea velocity, monitoring of deep-ground micro-vibration, detection of space-based space target micro-motion, non-destructive test in biomedical, sensing of Computerized Numerical Control (CNC) machine tool, equipment of intelligent agricultural machinery. This report mainly introduces the basic principle and research background of laser feedback interference technique, application of all-fiber structure laser frequency-shifted interference technique associated with the other related research work.

Prof. Shi Jiaming

National University of Defence Technology, China


Biography: Prof. Shi Jiaming have been with the National University of Defence Technology. My research interests include infrared characteristics of objects, functional infrared materials and application of low temperature plasmas.

Title: Research of multi band spectral characteristics of photonic crystals

Abstract: Photonic crystals (PCs)show special spectrums due to their unique configurations. These spectral spectrums can be utilized to modify the transmission of EM waves. In this speech, we will discuss the design of PCs which exhibit special spectrums in visual light and infrared bands, which may alter the detectability of objects covered by these PCs. Experimental results will also be given, which are in good agreement with theoretical ones.

Title: Advanced photoelectric detection and the influence of strong light on photoelectric detection

Abstract: With the development of technology, advanced optoelectronic detection technology is gradually being applied to fields such as environmental monitoring and target recognition, providing more refined and rich information for target detection. However, under strong or backlight conditions, the detection performance of the photoelectric detection system is limited. The factors affecting the detection system under such conditions are analyzed, and some strong light suppression detection ideas are proposed.
