The real part of the in-plane optical self-energy data in underdopedBi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+\delta}$ (Bi-2212) and ortho IIYBa$_{2}$Cu$_{3}$O$_{6.5}$ contains new and important information on thepseudogap. Using a theoretical model approach we find that the density of statelost below the pseudogap $\Delta_{pg}$ is accompanied with a pileup just abovethis energy. The pileup along with a sharp mode in the bosonic spectralfunction leads to an unusually rapid increase in the optical scattering rateand a characteristically sloped peak in the real part of the opticalself-energy. These features are not found in optimally doped and overdopedsamples and represent a clearest signature so far of the opening of a pseudogapin the in-plane optical conductivity.

Evidence for a pseudogap in underdoped $Bi_2Sr_2CaCu_2O_{8+\delta}$ and $YBa_2Cu_3O_{6.50}$ from in-plane optical conductivity measurements
