Even if the researchers succeed in that task, the resulting device would be considered an optically pumped laser, which works only when an external light source stimulates it.

Gould, retired and living in Kinsale, Va., also recently won a 10-year court battle to uphold his patent for an optically pumped laser amplifier (SN: 3/20/82, p.199).

The end of a long patent fight

Optically pumped lasers have been achieved from various ZnO micro/nanostructures, such as thin films [1], powders [2], microtubes [3], nano/microwires [4-6], nanobelts [7], nanonails [8], microspheres [9], and nano/microdisks [10,11] by single-photon absorption in which ZnO serves as both active gain medium and optical resonant cavity.
