                         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.",
