Abstract

Previous measurements of intraband carrier relaxation in semiconductors have employed the equal-pulse correlation technique to observe a saturation effect in the transmission of short pulses through a thin sample.1 Relaxation times were extracted from the recorded data by fitting it to the convolution of the pulse autocorrelation and an exponential response function. This requires some estimate of the coherent contribution to the signal, which in turn depends on parameters that are not directly accessible to experiment.
