Abstract

We present comprehensive modeling of gain-enhanced metallic nanoshells, analyzing their lasing characteristics through optical Bloch equations coupled to free-electron dynamics. By comparing symmetric and antisymmetric plasmon resonances and examining detuning effects between gain and resonance frequencies, we identify optimal conditions for emission thresholds, spectral tunability, and frequency pull-out dynamics.
