摘要：

Spectroscopy on a single ZnSe quantum well characterized by a sharp exciton resonance (Delta E = 0.6 meV) shows how a gas of interacting excitonic molecules induces blue-green laser emission in an optically pumped heterostructure at cryogenic temperatures; Spectrally resolved four-wave-mixing experiments yield a molecular binding energy of 5 meV. However, the lasing occurs in an electron-hole density regime, where strong many-exciton interaction effects are evident.
