Understanding excited carrier dynamics in semiconductors is crucial for the development of
photovoltaics and efficient photonic devices. However, overlapping spectral features in …

The electronic character of photoexcited molecules can abruptly change at avoided
crossings and conical intersections. Here, we report direct mapping of the coupled interplay …

Gas-filled hollow-core fiber (HCF) pulse post-compressors generating few-to single-cycle
pulses are a key enabling tool for attosecond science and ultrafast spectroscopy. Achieving …

We demonstrated the generation and characterization of 9.7 fs, 180 μJ pulses centered at
385 nm via the frequency doubling of few-cycle near-infrared pulses. Both moderate …

We present an implementation of dispersion-scan based on self-diffraction (SD d-scan) and
apply it to the measurement of over octave-spanning sub-4-fs pulses. The results are …

Temporally short X-ray pulses are an indispensable tool for the study of electron transitions
close to the Fermi energy and structural changes in molecules undergoing chemical …

In this Letter, ultrashort blue pulses spanning 350–500 nm are generated by combining the
broadband frequency doubling technology with the two-stage multiplate continuum (MPC) …

In this work, 85? µJ, 5.5? fs pulses spanning 350–500? nm with 96% energy concentrated
on the main pulse are generated by pulse compression using a helium-assisted, two-stage …

We demonstrate the generation, spectral broadening and post-compression of second
harmonic pulses using a thin beta barium borate (BBO) crystal on a fused-silica substrate as …

We demonstrate efficient generation of continuous spectrum centered at 400 nm from solid
thin plates. By frequency doubling of 0.8 mJ, 30 fs Ti: sapphire laser pulses with a BBO …
