摘要：

We demonstrate that half-wavelength facet coatings of Al2O 3 can arrest the growth of pulsations in the output intensity of (Al,Ga)As double-heterostructure lasers during cw aging in a 70°C dry nitrogen ambient while also eliminating an initial mode of degradation. These concurrent effects of the coatings suggest a common origin for the aging-induced pulsations and the initial degradation and also support a recently proposed model for the origins of pulsations.
