Jones, I don't think the Letts-Cravens experiment is similar to Holmlid at all. They used two calibrated wavelength lasers superimposed on the cathode. They found that when the lasers were separated by a specific frequency difference in the 10-20 THz range, there was a peaking in the XP. For there to be a frequency difference effect, there must be a nonlinearity - likely a surface plasmon at the cathode surface - that allows the difference frequency to form. The difference frequency of 10-20 THz where there was a peak in XP is VERY suggestive of phonon stimulation, something compeletely different than Holmlid's experiment.
