The luminescence properties of GaP (Te) have been investigated under strong optical pumping by a ruby laser (two-photon excitation) at 80 degreeK. Stimulated emission is observed at 5413 A with a pumping threshold of 13 MW/ cm$sup 2$. Gain measurements at various intensities are also reported. (AIP)
