Figure Legend:
Examples of (a) transient absorption data acquired at small values of the delay time between pump and probe, − 2 < t< 2 ps; and (b) time domain thermoreflectance data acquired at large delay times. 0.1 < t< 3 ns. Vin and Vout are the in-phase and out-of-phase signal from rf lock-in amplifier, respectively. The peak of the transient absorption caused by two-photon absorption at t = 0 (marked by an arrow in (a)) is used to measure the temperature of the sample. The ratio signal, -Vin/Vout, at t = 0.5 ns (marked by an arrow in (b)) is used to measure the effective thermal conductance of the Pt/water interface.
