Dual combs are an emerging tool to obtain unprecedented resolution, high sensitivity, ultrahigh accuracy, broad bandwidth, and ultrafast data updating rate in the fields of molecular spectroscopy, optical metrology, as well as optical frequency synthesis.
提出了一种基于预扭制保偏光纤(PMF)Sagnac环形镜结构的光纤扭转传感器,该传感器可以同时实现扭转方向的判别和扭转角度的测量。此结构的传感部分由熔接在两段2 mm长的多模光纤(MMF)中间2 cm长预扭制的熊猫型PMF构成,通过透射光谱中谐振波谷波长或功率变化的测量,实现扭转方向判别和扭转角度的测量。实验结果表明,该传感器具有较高的灵敏度。逆时针扭转时,谐振波谷波长随着扭转角度的增大发生蓝移,

We present a novel photonic Doppler velocimetry (PDV) design for laser-driven shock-wave experiments. This PDV design is intended to provide the capability of measuring the free-surface velocity of shocked opaque materials in the terapascal range. We pres

A structure which consists of photoresist film sandwiched by Ag nano-particle and metal film is proposed to modify localized hotspot both in transversal and longitudinal direction. It shows that there is strong plasmonic coupling between Ag nano-particle
采用射频磁控溅射法在蓝宝石衬底上制备了Hf∶ZnO (HZO)薄膜,研究了氧气流速和退火温度对薄膜微观结构和光电性能的影响。为了提高薄膜的结晶性,将制备的薄膜在800 ℃下退火30 min,并自然冷却到室温。测试、分析了退火后薄膜的微观结构和光电性能。研究发现,随着氧气流速从0增加到0.6 mL/min,薄膜的致密度逐渐增大,电阻率逐渐降低,而当氧气流速继续增大到0.8 mL/min时,薄膜的结晶性恶化,电阻率突然升高。氧气流速为0.6 mL/min时制备的薄膜光电性能最佳,利用傅里叶红外光谱仪和霍尔测试
