摘要：

We have measured the electroabsorption of a CdZnSe/ZnSe/ZnMgSSe single quantum-well laser diode at photon energies close to room temperature laser emission. At the laser photon energy an pronounced increase of the absorption coefficient alpha with increasing reverse bias voltage was observed. The obtained spectral dependence of the absorption coefficient is similar to bulk material what can be explained by the field ionization of the exciton and the Franz-Keldysh effect. A possible application of the laser diode as saturable absorber is demonstrated.
