Scatter Plot from Scientific Research

Two colour absorption power-dependent ionisation rate Γ (slope of γ λ ) versus wavelength (error bars = ± 1σ ). Second laser pulse (varied in length, wavelength and power) is applied together with PLE lasers at low power. Fit with Fermi distribution yields a threshold of 948 nm for the charge conversion of VSito VS2− , compare ( c ). Schematic pulse sequences for ( a , b ) shown on top. Inset: exemplary ionisation rate γ versus power of second laser for a wavelength of λ = 900 nm again linearly fitted. All error bars are equivalent to ± 1 σ .
