AbstractIn this work we study the defects responsible for the degradation of high power AlGaAs based laser bars. The mirror and cavity degradations are studied by spectral cathodoluminescence (CL) imaging. Following the analysis of the CL images the main defects generated during the laser operation are revealed, both facet and intracavity defects are observed. A thermomechanical model is used to describe the very beginning of the defect formation. The defects are formed by a local plastic deformation induced by local heating at defects.

Cathodoluminescence Study

ABSTRACTHydrothermal ZnMgO crystals were studied by cathodoluminescence. The high energy shift of the excitonic luminescence demonstrates the Mg incorporation in the ZnO lattice in at a few percent. The spectral parameters of the luminescence emission show a marked dependence of the incorporation of defects and Mg on the growth facet. This growth sector selectivity shows similar trends to those observed in hydrothermal ZnO crystals. The in depth distribution of Mg was studied varying the acceleration voltage of the excitation e-beam, showing a slight accumulation of Mg close to the surface.
