Abstract We investigate the propagation of optical pulses through two different solidstate optical materials, ruby and alexandrite, for which the group velocity can be very small (vg c) or superluminal (vg c or negative). We find that for smooth pulses the fractional delay or advancement is maximized through the use of pulses with durations comparable to the response time of the physical proces...
