Einstein established the quantum theory of radiation and paved way for modern laser physics including single-photon absorption by charge carriers finally pumping an active gain medium into population inversion. This can be easily understood in particle picture light. Using intense, ultrashort pulse lasers, multiphoton has been realized. In this nonlinear interaction regime, excitation inversion depend not only on photon energy but also intensity incident light, which still described solely We demonstrate here that lowering significantly pump further enables lasing semiconductor nanowires. The extremely high electric field bends bands tunneling electrons from valence to conduction band. light acts classical Coulomb force is entirely due wave nature electrons, thus becomes independent frequency depends
