title: The Design and Development of a Solar-Powered AUV with an Unconventional Shape
title: The Design and Development of a Solar-Powered AUV with an Unconventional Shape

description: Unmanned underwater robots have the ability to carry various sensors to perform underwater tasks in the inaccessible environment for humans. Solar-powered AUVs can use sustainable natural energy to be capable of offering long-term mission support. This paper presents the ongoing development work on the overall design of a solar-powered AUV(SAUV). An overview of the SAUV and its design goals, especially an unconventional vehicle shape due to integrating solar panels with the SAUV, will be described. With a weight of 260kg, length of 2 meters, width of 2 meters, the SAUV is propelled by a specially designed vectorial thruster, with a maximum speed of 2knots. The AUV is equipped with multiple commonly used sensors as the perception system. The autonomous operation of SAUV is achieved by using Robotics Operating System (ROS). The SAUV has undergone at sea testing in Nanshan Harbor, Sanya. Overall, the test results achieve satisfactory effects.

title: The design and application of a novel vectored thruster for special-shaped AUV

description: AUVs, as the primary platform, have significantly contributed to underwater surveys in scientific, and military fields. Enhancing the manoeuvrability of autonomous underwater vehicles is crucial for their development. A novel vectorial thruster is present in this paper. The thrust-vectoring mechanism of the novel vectorial thruster has two rotational degrees of freedom achieved by a linear actuator and a steering engine. The effectiveness of the AUVs is notably enhanced at low forward speeds with the specially designed thrust-vectoring mechanism. A theoretical analysis has been conducted to investigate and verify the kinematics of the thrust-vectoring mechanism. the spatial attitude control test and propulsive force test of the vectorial thruster are made to evaluate its performance. Finally, open-hoop control was applied to the control of a real SAUV, and experiments were conducted in a water tank The experimental results demonstrate that the performance of this type of vectorial thruster is acceptable, and the design is worthy of further research.

title: Characterization of electromagnetic pulse generated from plasma associated with laser filaments-excited aluminum alloy in air
title: 飞秒激光空气成丝-固体靶作用产生微波辐射特性研究

description: Femtosecond laser filament-generated plasma can generate electromagnetic pulses (EMPs).These pulses may reduce the instrument’s precision, and, hence, influence the accuracy of theexperimental results. They may even cause widespread disruption by disabling of the electroniccontrol systems or distribution networks of power plants. This study investigated the characteristicsof EMPs generated from the interaction of filament-generated plasmas with a solid target in air. In thisstudy, ultrafast laser filamentation was used to produce plasma, which was focused on a 3 mm-thickaluminum (Al) alloy target for interaction, and the spatial distribution and main contributors of theEMPs were systematically and extensively studied. The results showed that the EMPs generatedfrom ultrafast laser filament interaction with the Al alloy target had the following characteristics: theEMP energy generated from laser filament interaction with solid targets is tens of times higher thanthat generated only from the femtosecond laser filament; the maximum EMP signals appeared ata 20–80detection angle. The relationship between the energy of EMPs and the width and energyof the laser pulses is presented and discussed. These findings are beneficial for gaining insight intothe EMP generation mechanism, spatial distribution, and transmission, and for providing moreinformation for the design of EMPs’ shielding.

title: Improved performance of Faraday effect based on Pr3+, Ce3+ co-doped terbium gallium garnet crystal

description: A novel transparent Pr3+, Ce3+ co-doped terbium gallium garnet (Pr,Ce:Tb3Ga5O12, Pr,Ce:TGG) single crystal was grown by the Czochralski technique. Its transmittance is about 80% in 600~1300nm wavelength range except for special absorption peaks. The Vertdet constants (V) of Pr,Ce:TGG crystal at 532nm and 632.8nm are -230 and -153 rad·T-1·m-1, which are both larger than those of terbium gallium garnet (Tb3Ga5O12, TGG) crystal. The thermal conductivity of Pr,Ce:TGG crystal is 3.35 W·m−1·K−1 at 300K. Bulk laser induced damage threshold (LIDT) of Pr,Ce:TGG crystal was measured to be 15 J·cm-2 by R-on-1 test. The results show that Pr,Ce:TGG crystal as magneto-optical material has potential ability to be used in optical isolators.
