But, I think you missed the point (maybe). Achieving an XH stimulation with such weak lasers, and in particularly at a required resonance in difference frequency in the THz range, is a key probe of the effect. Yes, you might be able to generate some enhancement by brute force, but it would cloud the probe of the nature of the effect. The efficiency will be low for conversion of the small power laser signal pair to a THz difference signal, so it means that the THz signal at the surface was extremely weak. Yet at the THz resonance, it had a very significant effect on the XH. The THz signal was extremely weak compared to the XH that was stimulated and was clearly non-ionizing. That THz-to-XH gain at such a low level is a key evidence of phonon involvement IMHO.
