Abstract
We report on the use of picosecond duration laser pulses to generate picosecond acoustic pulses in metal films on the order of 200 nm thick. The acoustic pulses are detected by means of transient piezoreflectance measurements. We demonstrate the use of a thin metal overlayer to enhance the piezoreflectance signal.Keywords
