| 1 | Researching the 915 nm high-power and high-brightness semiconductor laser single chip coupling module显示文摘Based on the high-speed development of the fiber laser in recent years, the development of researching 915 nm semiconductor laser as main pumping sources of the fiber laser is at a high speed. Because the beam quality of the laser diode is very poor, the 915 nm laser diode is generally based on optical fiber coupling module to output the laser. Using the beam-shaping and fiber-coupling technology to improve the quality of output beam light, we present a kind of high-power and high-brightness semiconductor laser module, which can output 13.22 W through the optical fiber. Based on 915 nm GaAs semiconductor laser diode which has output power of 13.91 W, we describe a thoroughly detailed procedure for reshaping the beam output from the semiconductor laser diode and coupling the beam into the optical fiber of which the core diameter is 105 μm and the numerical aperture is 0.18. We get 13.22 W from the output fiber of the module at 14.5 A, the coupling efficiency of the whole module is 95.03% and the brightness is 1.5 MW/cm^2 -str. The output power of the single chip semiconductor laser module achieves the advanced level in the domestic use. | Xin Wang Cuiluan Wang Xia Wu Lingni Zhu Hongqi Jing Xiaoyu Ma Suping Liu | 2017 | Journal of Semiconductors2017，38，2： | 3 |
| 2 | The optimization of hydrothermal process of MoS2 nanosheets and their good microwave absorption performances显示文摘In this study,flower-like MoS2 constructed by nanosheets was synthesized by a simple hydrothermal method.The hydrothermal process was optimized and the effects of hydrothermal condition,including reaction temperature,reaction time and the ratio of Mo source to S source(Mo:S)in precursor,on microwave absorption performances and dielectric properties were investigated.Our results showed that when the reaction temperature was 180℃,the reaction time was 18 h,and the Mo:S was 1:3.5,the synthesized MoS2 had the best performance:Its minimum reflection loss could reach-55.78 dB,and the corresponding matching thickness was 2.30 mm with a wide effective bandwidth of 5.17 GHz.Further researches on the microwave absorption mechanism revealed that in addition to the destructive interference of electromagnetic waves,various polarization phenomena such as defect dipole polarization were the main reasons for microwave loss.We believe that MoS2 is a candidate for a practical microwave absorbent. | Xiaoyu Lin Jing Wang Zengyong Chu Dongqing Liu Taotao Guo Lingni Yang Zhenyu Huang Sitong Mu Shun Li | 2020 | Chinese Chemical Letters2020，31，5： | 2 |
