内容記述 | Experimental results are reported on the longitudinal mode characteristics of PbSnTe buried heterostructure laser diodes operating at 10 microns. It is found that both 'wide' (5 microns) and 'narrow' (2 microns) stripe lasers operate in a single longitudinal mode over a range up to two times the threshold, as expected on the basis of the homogeneous gain model. However, a systematic change to multimode operation is found above this pumping level, which this model cannot explain. The observed phenomenon is explained by spectral inhomogeneity with an intraband relaxation time of the order of 2 ps. |
