(57) [Summary] A continuously pumped and Q-switched Nd: YAG laser (10) is plated on the inner wall surface (79, 126) of a passage (72, 74) in a multilayer electronic device (80). Frequency converted to provide ultraviolet light (62) for The parameters of the output pulse (62) are selected to facilitate a substantially uniform deposition of plating material particles that are explosively vaporized from the substrate (124) onto the inner wall surfaces (79, 126). These parameters typically include at least two of the following: high average power measured over the beam spot range of greater than about 100 milliwatts, temporal pulse width of less than about 100 nanoseconds, about Spot diameter less than 50 microns, and repetition rate greater than about 1 kilohertz. |
