Generation of broadband THz transients via metallic spintronic emitters driven by 20-fs pulses at 1030 nm

We explore power and bandwidth scaling for the generation of highly-temporally-confined THz transients from spintronic emitters, driven by the 250-fs and 20-fs pulses of a high-power 28-MHz Yb-based laser, spectrally centered at 1030 nm.
