    "abstract": "We develop models for the propagation of intense pulses in solid state media\nwhich can have either saturated absorption or exhibit reverse absorption . We\nshow that the experiments of Bigelow {\\it et al.}[Phys. Rev. Lett. {\\bf 90},\n113903 (2003); Science {\\bf 301}, 200 (2003).] on subluminal propagation in\nRuby and superluminal propagation in Alexandrite are well explained by\nmodelling them as three level and four level systems coupled to Maxwell\nequations. We present results well beyond the traditional pump-probe approach.",
