This paper applies a recent many-body theory to investigate the corrections to semiconductor laser gain and carrier-induced refractive index. Our results show nonnegligible modifications to these quantities and demonstrate the importance of band-gap renormalization and Coulomb enhancement. The influence of the many-body Coulomb effects on filamentation effects in semiconductor lasers is investigated.
