Abstract Designing an organic polymer photocatalyst for efficient hydrogen evolution with visible and near-infrared (NIR) light activity is still a major challenge. Unlike the common behavior of gradually increasing charge recombination while shrinking bandgap, we present here series nanoparticles (Pdots) based on ITIC BTIC units different π-linkers between acceptor-donor-acceptor (A-D-A) repeated moieties polymer. These polymers act as single H2 under both NIR light, without combining or...

We successfully compressed 190-fs, 1030-nm pulses 42 fs with 590 μJ input pulse energy, which 5.5 times higher than that obtained by a Gaussian setup of the same footprint. High throughput (86%) and high intensity-weighted homogeneity (>98%) have also been achieved. This experiment confirms great potential shaping energy up-scaling nonlinear compression.
