The development of amplified luminescence fluxes in powerful InGaAs/AlGaAs laser diode arrays (lasing wavelength 940-960 nm) has been studied experimentally and theoretically at pump levels above the threshold value. Flux density values for amplified luminescence propagation along (1.88⋅10 9 W/m 2 ) and across (1.21⋅10 9 W/m 2 ) the laser diode array cavity axis have been evaluated for the threshold pump level at room temperature (293 K). The contribution of the recombination rate induced by the amplified luminescence to the threshold current generation of the laser diode array reaches 7%. It has been shown that the amplified luminescence flux density is increased by 49% as the pump level rises from one to three threshold values.

Spatial and spectral characteristics of lasing from ZnxCd1−xS (0 ≦ x ≦ x 0.5), CdSexS1−x (0 ≦ x ≦ 0. 25), and CdS single crystals are investigated at temperatures 4.2, 77, and 300 K under nitrogen laser excitation. The samples are vapour‐grown platelets as well as hexagonal‐prism‐shaped “needles”. The inconsistence of the previously wide‐spread Fabry‐Perrot cavity model is shown and the interpretation is proposed in terms of a new model, namely, that of partial cavities (PC) each of them being a rectangular microbox (or microprism for “needles”). The importance of intermode scattering and optical coupling between the different PC in the process of lasing is shown experimentally.
