That and wikipedia brings you quite far. It's a good idea to try and find out yourself, then you can ask more specific questions.
Unless you're satisfied with "a semiconductor is basically a diode where the electron-hole pairs in the P-N junction are the population inversion created by a potential across the diode. Add the facets for feedback and you have a cavity with gain."
