abstract = "We report the first observation, to our knowledge, of ultraviolet
upconversion random laser (RL) emission from ZnO films excited by
three near-infrared photons in the femtosecond regime. The
nanostructured films of ZnO were fabricated on a silicon substrate
using the Plasma Immersion Ion Implantation and Deposition method.
The band-to-band excitation process led to RL emission with
incoherent feedback, emitting light at approximate to 390 nm. RL
emissions excited by one and two photons were also verified using
the same pump geometry. The results are discussed and a comparison
with previous studies is presented.",
