This work scrutinizes the time-average excitation rate (TAER) among the GaAs quantum dot (QD) eigenstates under the aegis of Gaussian white noise (GWN) and the parity of the anharmonic potential (odd/even). GWN connects with the system by additive or multiplicative mode. The said excitation of the ground state population has been triggered by an external field which may be a polychromatic radiation field (PRF), or pulsed field (PF) or chirped pulsed field (CPF). The study reveals the subtle nuances of the interplay between noise (additive or multiplicative), anharmonicity (odd or even) and the external field (PRF, PF or CPF) that finally govern the attributes of the TAER diagrams. The TAER profiles exhibit persistent growth, persistent decline, maximization (important in view of production of prominent nonlinear optical properties), minimization and saturation (relevant to the dynamic freezing). The findings appear useful for regulating the TAER among the GaAs QD eigenstates which have substantial technological relevance.
