Thin films of Er-implanted GaN are annealed with pulses of 31 ns duration from a KrF excimer laser. The degree of annealing is evaluated by measuring the Er photoluminescence at 1540 nm. The implantation dose is 4 × 1013-4 × 1015cm-2. The laser fluence is 0.15-0.88 J/cm2. The number of laser pulses is 102-5 × 104. A total heating time on the order of 1 ms is long enough to produce good structural reordering, and short enough to avoid decomposition. The results are compared with a numerical simulation of the heating as a function of time and depth in the sample.
