氧化铟锡薄膜在光学太阳反射镜上的应用

研究了光学太阳反射镜抗静电放电用氧化铟锡薄膜的设计原则.理论分析和实验结果表明,在将氧化铟锡(ITO)薄膜应用于光学太阳反射镜(OSR)表面防静电放电时,ITO薄膜的表面方阻R□不能小于5 kΩ@□-1,否则会导致OSR的太阳光谱吸收率增加.建议取R□=5～106kΩ@□-1,薄膜厚度d=(150～200)×10-10 m.同时必须保证ITO薄膜接地效果良好,否则会使OSR表面充放电现象更加严重.

Spectrum characteristics and pump wavelengths of Nd3+-doped double-clad fiber

Conclusion The optimum wavelength of Nd³⁺-doped double-clad fiber laser or amplifier made in China is near 830 nm. The efficiency of Nd³⁺-doped double-clad fiber devices pumped by 820-nm laser is low due to ESA. In order to increase the photochemical stability of the outer cladding, the material of the outer cladding must be advanced.     

Optical fiber grating bistability

It is proposed that a segment of Er-doped fiber with a couple of fiber gratings on the ends may be used as a novel optical bistability device with low power and high speed. Operation and bistability threshold of device are analysed in accordance with the distributed feedback couple-mode theory and the nonlinear characteristic of Er-doped fiber. It is shown that a nanoseconds microwatts bistable operation of a centimeter device is realizable under nowaday technological condition.
