            Abstract : 
Both cavity facets of AlGaAs semiconductor lasers were fabricated using a reactive ion beam etching (RIBE) technique. The etched mirror´s reflectivity is estimated to be 0.24 and its scattering loss 0.15. Both facets dry-etched lasers at 70 degrees C heat-block temperature and 5 mW light output power showed no remarkable deterioration for over 3500 h.
