20. -1 [typical for polymers: E. Kang, J. Y. Bae, and B. S. Bae, J. Solgel Sc. Tech. 26, 981 (2003)] an estimated maximum pumpinduced temperature increase ∼100 K would cause a modulation <0.001%, much lower than the noise level of the experiment.

23. The GHz mobility was reported in J. M. Warman et al., J. Phys. C: Solid State Phys. 14, 9935 (2002). The carrier density in these experiments was calculated assuming that all the energy deposited in the sample was used to generate charges. As this efficiency is generally much smaller than 100%, this sets a conservative lower limit for the GHz carrier mobility.
