FIG. 3.

(Color online) (a) VSL data for sample R taken from . The solid lines are fitting curves using the one dimensional amplifier model. (b) VSL data for sample G taken from . (c) VSL data for sample O taken at . (d) Optical loss/gain coefficients obtained from the fitting curves vs photon energy. All the measurements were taken with a pump fluence. The time gate was set to detect only the fast component (from ).

FIG. 4.

(Color online) (a) Sample G: VSL data taken at with different pump fluences, (square), (circle), (up triangle), (down triangle), (diamond), and (left triangle). (b) Optical loss coefficient vs normalized pump intensity.
