这是个什么效应？？pump effect？？貌似和荧光有关

请问各位高手，pump effect 是什么东东？？貌似和荧光有关？？下面是这个东东的背景，希望各位帮帮忙。。。在此谢过了！！ The Ag cluster in solution has been prepared by a microwave high-pressure procedure. There is a maximum resonance Rayleigh scattering (RRS) peak at 425 nm (7.06×10 14 Hz) and a smaller RRS peak at 850 nm (1/2×7.06×10 14Hz) by synchronous scattering at lex=lem（激发波长=发射波长）. It is a nonlinear optical medium. When scattering the emission wavelength (lem发射波长) as the excited wavelength (lex激发波长) at 425 nm (7.06×10 14 Hz), a maximum RRS peak was observed at 425 nm (7.06×10 14Hz). A 1/2 fraction scattering peak at 850 nm (1/2×7.06×10 14Hz) was also investigated. When lex（激发波长） is at 850 nm(3.53×10 14 Hz), a frequency-doubling scattering peak at 425 nm is observed, and a RRS peak is displayed at 850 nm (3.53×10 14 Hz). When thelex is two times longer than the maximum RRS wavelength (the strongest wavelength of pump band lpb) of an atomic cluster, a nonlinear scattering frequency-doubling peak (lpb) exhibits at half of the lex（激发波长）, which is stronger than the RRS peak. This phenomenon is defined as pump effect. |
