We make a rigorous exploration of the profiles of a few diagonal andoff-diagonal components of linear αxx, αyy, αxy andαyx, first nonlinear βxxx, βyyy, βxyy andβyxx, and second nonlinear γxxxx, γyyyy, γxxyyandγyyxxpolarizabilities of quantum dots under the influence of external pulsed field.Simultaneous presence of additive white noise has also been considered. Thequantum dot contains dopant described by a Gaussian potential. The numbers ofpulse and the dopant location have been found to fabricate the said profilesjointly. The β components display greater complexity in theirprofiles in comparison with the α and γ counterparts. The presence of noiseprominently enhances the influence of dopant coordinate on the polarizabilityprofiles, particularly for α and γ components. However,for β components, the said influence becomes quiteevident both in the presence and absence of additive noise. The study revealssome means of achieving stable, enhanced, and often maximized output ofnoise-driven linear and nonlinear polarizabilities.
