Transient optical reflectivity measurements. a Transient reflectivity changes probed at the wavelength of 1100 nm at various sample temperatures. Solid lines are fits with the fitting errors showing as error bars in b. b Recovery time constants of the transient reflectivity change as a function of sample temperatures. The solid line is a fit of tslow to the scaling law \(\sim (1 - T/T_{\mathrm c})^{ - \Delta }\)
