Phase-correlated nondirectional laser emission from the end facets of a ZnO nanowire

Nano Lett. 2006 Dec;6(12):2707-11. doi: 10.1021/nl0616227.


We investigated the laser emission from individual ZnO nanowires and observed an interference pattern due to coherent laser emission from the wire end facets. Comparison with numerical simulations shows that the laser light is emitted nearly spherically from the wire ends. The energy spacing between sharp lasing modes scales with the inverse length of the nanowire; thus, laser emission peaks correspond to Fabry-Pérot modes of the nanowire cavity.
