By employing a simple hemispherical resonator configuration, laser oscillations were observed from vapor-grown undoped CdS platelets pumped by 4-nsec dye laser pulses. The lasing shifted toward longer wavelengths from 4885 to 5180 Å by varying the temperature of the samples from 5 to 250 °K. The laser emission observed at low temperatures is attributed to the acoustic-phonon-coupled I1 bound-exciton transitions. The resonant behavior of this laser process is also reported.
