    • The present invention relates to a 3-color multiplex CARS spectrometer. In the 3-color multiplex CARS spectrometer, Raman resonance is achieved for multiple molecular vibrations of a sample by the combination of a short-wavelength pump beam generated by a broadband laser light source and a long-wavelength Stokes beam generated by a stable laser light source, and another short-wavelength laser beam having a narrow linewidth is then introduced separately to serve as a probe beam that interacts with the laser-driven sample, thereby generating CARS spectral signals whose wavelength components can be resolved. Accordingly, the 3-color multiplex CARS spectrometer solves problem of the conventional 2-color multiplex CARS spectroscopy in which the wavelength decomposition of CARS signals, necessary for high spectral resolution, is not possible with broadband pump light causing the CARS spectrum distortion.
    • 本发明涉及一种三色多重CARS光谱仪。 在三色多重CARS光谱仪中,通过将由宽带激光光源产生的短波长泵浦光束与由稳定的激光产生的长波长斯托克斯光束组合,实现了样品的多分子振动的拉曼共振 源和另一个具有窄线宽的短波长激光束然后被单独引入以用作与激光驱动样本相互作用的探测光束,从而产生其波长分量可以被解析的CARS光谱信号。 因此,三色多路CARS光谱仪解决了传统的双色多重CARS光谱的问题,其中对于高分辨率分辨率需要的CARS信号的波长分解在宽带泵浦光引起CARS频谱失真是不可能的。

    • A fuel cell stack induces smooth current collection and liquid or gas flow without using a heavy bipolar plate. The fuel cell stack includes: a membrane and electrode assembly (MEA) in which an electrolyte membrane is disposed between a cathode electrode and an anode electrode; a current collector disposed in the MEA to form an electrical path with an adjacent MEA; and a non-conductive separation plate disposed between the MEA and the adjacent MEA, the non-conductive separation plate forming flow channels to supply a liquid or gas to the cathode electrode and the anode electrode. A fuel cell stack structure having the above structure is simple and lightweight as the MEA includes a thin and lightweight non-conductive polymer separation plate and a current collector to connect adjacent MEAs.
