Abstract
We report the observation of a supercontinuum (SC) in aqueous CdTe/ZnSe quantum dots (QDs) pumped by 800-nm femtosecond laser pulses based on simulations and experiments. For an average nanocrystal of 5.5 nm in size and a weight concentration of 5  mg/mL, the SC generated with a low-input energy range exhibits high optical to optical conversion efficiency. The measured SC spectrum exhibits spectral broadening that is significantly influenced by the nonlinear coefficient of the QDs. This nanoparticles-based SC effect may have special applications for optical coherence imaging and ultrashort pulse compression.
