Passively mode-locked Nd: LuAG laser at 1338 nm
2016年 -徐洵-《Optical Materials Express》
摘要:A stable passive mode-locking Nd: LuAG laser at 1338 nm with a semiconductor saturable absorber mirror (SESAM) is demonstrated for the first time. The mode-locking Nd: LuAG laser yielded a maximum average output power of 0.54Wwith a slope efficiency of 10.2%. The corresponding shortest pulse duration was 18.3 ps with a signal-to-noise ratio of 63 dB under a pulse repetition rate of 46.9 MHz . This work indicates that the Nd:LuAG crystal is a promising candidate for realizing picosecond lasers around 1.3 μm spectral region. ? 2015 Optical Society of America.
A system framework for OKP product planning in a cloud-based design environment
2016年 -徐洵-《Robotics and Computer-Integrated Manufacturing》
摘要:Nowadays, one-of-a-kind (OKP) companies, which generally operate in an 'engineer-to-order' business mode, strive to deliver individualized products with quality to achieve customer satisfaction. Thus, an accurate and prompt analysis of customer requirements (CRs) in the early design stage is critical to its success. However, most OKP companies are small or medium-sized enterprises (SMEs). Due to the limited resources and low product planning budget, they often cannot obtain abundant CR information nor can they afford the expense of complicated planning process. To address these issues, a system framework is proposed in support of OKP product planning process in a cloud-based design (CBD) environment. The challenges and future market niches of OKP companies are presented. The comparison of typical distributed systems shows that CBD, which utilizes advanced information technologies and business model, has advantages in providing sufficient resources, decreasing product development time span for OKP companies in a cost-efficient way. This article describes the proposed system architecture, the business interaction process and the information communication among customers, designers and marketing analysts at the product planning stage. To validate the proposed framework, a prototype system module MyProduct is under development in the CBD environment with an illustrative example. ? 2016 Elsevier Ltd.
Tokamak Power Exhaust with the Snowflake Divertor: Present Results and Outstanding Issues
2016年 -徐洵-《Journal of Fusion Energy》
摘要:A snowflake divertor magnetic configuration (Ryutov in Phys Plasmas 14(6):064502, 2007) with the second-order poloidal field null offers a number of possible advantages for tokamak plasma heat and particle exhaust in comparison with the standard poloidal divertor with the first-order null. Results from snowflake divertor experiments are briefly reviewed and future directions for research in this area are outlined. ? 2015, Springer Science+Business Media New York.
