High average and peak power femtosecond large-pitch photonic-crystal-fiber laser
(2011)We report on the generation of high-average-power and high-peak-power ultrashort pulses from a mode-locked fiber laser operating in the all-normal-dispersion regime. As gain medium, a large-mode-area ytterbium-doped ... -
Observation of biexcitons in the presence of trions generated via sequential absorption of multiple photons in colloidal quantum dot solids
(IEEE, 2012)Multi exciton generation (MEG) and multi exciton recombination (MER) in semiconductor quantum dots (QDs) have recently attracted significant scientific interest as a possible means to improve device efficiencies [1-5]. ...
