Experimental Data for Attosecond Spectroscopy via High Harmonic Generation

Wenhao Yu's Ph.D. thesis supporting data describes an attosecond-resolution spectroscopy apparatus and a transient absorption experiment on SiO2. The dataset likely contains measurements from a home-built apparatus using an 800 nm laser and its high harmonics, with spectral focus near a 10.85 eV band gap. The data was last updated on 2026-05-19.

Use Cases

• Modeling excitonic dynamics based on the observed absorption feature attributed to the AC Stark shift
• Benchmarking temporal resolution of spectroscopy apparatuses based on the described attosecond to few-femtosecond regime
• Analyzing spectral modifications near band gaps based on the investigation of the 10.85 eV region
• Simulating IR-XUV pump-probe experiments based on the described apparatus with sophisticated control systems

Strengths

• The description details a high-precision transient absorption experiment on SiO2.
• The apparatus includes two home-built XUV spectrometers and a commercial time-of-flight spectrometer.
• The work demonstrates observation of excitonic dynamics with attosecond temporal resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
