We have found evidence through optical spectroscopy that AgO is indeed generated in the laser plume during pulsed laser deposition of $YBa_2Cu_30_{7-8}$ (YBCO) thin films using Ag-doped YBCO targets. This supports our earlier conjecture that formation of AgO in the plume and its subsequent dissociation at the elevated substrate temperature (since AgO is unstable above $350^oC$) provides active oxygen to the YBCO lattice, thereby increasing oxygen incorporation during growth of YBCO thin films.
