“Höher Harmonische im optisch getriebenen Zwei-Niveau-System” (Higher Harmonics in an Optically Driven Two-Level System). Typically, a two-level system is driven with a resonant pulse, meaning the energy [...] energy of the two-level system, resulting in Rabi oscillations. However, the system can also be driven at one third of the transition energy, leading to a non-linear optical process known as higher harmonics [...] harmonics. To describe this process under pulsed excitation, one can solve the equations of motion. Unlike in the resonant case, the popular rotating wave approximation cannot be applied here, and the oscillations …
