ZnSe-ZnCdSe quantum well structures are the most likely candidate for the fabrication of commercial blue-green semiconductor lasers. Devices incorporating these wells have achieved room temperature cw lasing at 510nm with operating lifetimes of up to 100 hours. In this paper, the gain spectra of optically pumped ZnCdSe-ZnSe multiple quantum wells is measured over a range of temperatures and intensities. The calculation, which includes many body effects such as Coulomb enhancement and spectral broadening due to carrier scattering, gives excellent agreement with the experimental gain measurements.
