Abstract

Nonlinear optical effects have had a major impact on many fields in optics since their discovery. We developed a numerical simulation to investigate how Time-Dependent Schrodinger Equations (TDSE) of electrons travelling within atomic and molecular potential wells, propagated with Finite Difference Methods, and excited with different types of laser sources, can show nonlinear photonic output.

In particular, here we are interested in resonance conditions of these systems. The parameters of a laser source, as well as the source type, have a substantial impact on the system’s TDSE. With the right conditions, and knowledge of the system’s current energy state, we can effectively choose what energy state to move the system to. We can likewise reduce the energy state by choosing conditions matching transitions to lower states, reducing the energy state of the system and stimulating photonic output.

In this paper we will show the effects of laser source conditions both in and out of resonance, in several different atomic systems with potential wells, and resulting nonlinear photonic output for each combination of parameters.
