A streak optical pyrometer was used to infer the WDM temperature at the critical density by converting a measurable intensity of light, with appropriate temporal, spatial and spectral resolution, to an equivalent blackbody temperature at a given wavelength. Using a 532 nm interferometric filter, we were able to obtain temporally resolved measurements of the WDM temperature at the corresponding critical density. The experimental measurements are then compared with 1D MULTI-fs and RALEF-2D hydrodynamic simulations.
