Validity of Raman and transmission data reaffirmed

Abstract
The simple experimental test of blocking the 1.15-μm cw probe beam shows that Si luminescence is not a problem in our time-resolved transmission measurements. The phonon wave vector probed in our Raman experiments is q = 1.5×106 cm−1, so that the Raman experiment is, in fact, sensitive to direct phonon heating by carrier relaxation.
