Optimization of adaptive feedback control for ultrafast semiconductor spectroscopy

Optimized terahertz generation via optical rectification in ZnTe crystals

“…where ω 0 is the carrier angular frequency of the pump pulse and the derivatives, in this expansion, are respectively the group-delay dispersion GDD (φ 2 ), the third-order dispersion TOD (φ 3 ), and so on. Such a parameterization of the optical pulses was adopted in order to reduce the size of the parameter space to explore, thus simplifying the task of the algorithm [18]. Note that, in the same spirit, we also impose boundary conditions on the four phase parameters values.…”

Polarization and phase pulse shaping applied to structural contrast in nonlinear microscopy imaging

“…The pulse spectral profile is optimized without a priori knowledge of its nature by an evolutionary strategy as described in Refs. [47][48][49][50].…”

Influence of chirp on the femtosecond excitation of a semiconductor microcavity laser

“…The theoretical analysis shows that the observed dependence of both, the amplitude and the temporal evolution of the laser response, on the sign and amplitude of the quadratical chirp can be attributed to the excitation-induced dephasing process of the 1s plasma-resonance of the quantum-well barriers. [8][9][10] In this paper, we investigate the response of a semiconductor microcavity laser to chirped optical pumping. ͓DOI: 10.1063/1.2830700͔ Coherent control techniques are a widely used tool for manipulation and detection of complex interactions.…”
