The angular distribution of laser ablated silver in vacuum has been measured in situ with an array of quartz-crystal microbalances. The silver surface was irradiated by ns pulses from a Nd:YAG laser operating at 355 nm for fluences ranging from 0.7 J/cm(2) to 8 J/cm(2). The distribution is strongly peaked in the forward direction corresponding to cos(p) 8, where p varies from 5 to 12 for the largest beam spot, but is less peaked for the smallest beam spots. The total collected yield of ablated atoms is about 2 x 10(15) Ag atoms per pulse for the highest pulse energies.
