摘要：

Using optical gain spectroscopy we have examined the intrinsic factors governing the laser operation of ZnSe/(Zn,Mg) (S,Se)/(Zn,Mg) (S,Se) separate confinement heterostructures up to room temperature. At low temperatures (T < 80 K) the optical gain is of biexcitonic nature. Above 80 It, the threshold pump intensity grows steeply and the laser emission turns into recombination of a strongly correlated electron-hole plasma as described by a microscopic-theory approach.
