Hi, everyone. I am having a hard time finding explicit values of non-linear susceptibility tensor values for any sort of crystals. Specifically, I'm looking for values of a BBO crystal, but I would like to know where to find others for my future research. I should say that I am looking for the case of incident 800 nm light, but, at this point, anything pointing me in the right direction would be enough. Any help would be greatly appreciated.
