Low- and High-Order Optical Nonlinearities of Quantum Dots

Various potential applications of quantum dots (QDs) require knowledge their optical nonlinearities. In this review, the third-order nonlinearities responsible for saturable absorption, two-photon reverse and nonlinear refraction in QDs, as well high-order harmonics generation laser-induced plasmas containing are analyzed. The methods QD synthesis preparation strongly affect Above-mentioned studies QDs analyzed various (sources coherent extreme ultraviolet radiation, limiters, mode-lockers, etc.).
