Abstract
We have observed stable single-mode oscillation of optically pumped ve rtical-cavity surface-emitting lasers (i.e., without fabricated apertu re) in several high-order daisy modes. The surprising stability of the nodal lines of a daisy mode is explained as being due to the combined action of many microscopic defects; when a daisy mode is moved across the wafer, the effective correlation length of the orientation of the pinning is of the order of 1 mu m.
