银纳米微粒具有特定的吸收光谱和明显的共振瑞利散射(RRS)、二级散射(SOS)和倍频散射(FDS)光谱。

They have specific absorption spectra and there are obvious resonance Rayleigh scattering (RRS), second-order scattering (SOS) and frequency-doubling scattering (FDS) spectra.

同时试验对不同反射率的耦合腔镜以及倍频晶体ppktp的线性吸收对倍频效率的影响做出了深入讨论。

And we discuss the effect of the coupling mirror with different reflectivity and PPKTP crystal's thermal lensing effect led by linear absorption to the conversion efficiency.
