| Abstract: | Through the technology process of evaporating Si0 Au high reflecting coatings on GaAs laser back cavity surface, we analysed the coating characteristics. The reflectivity have been increased from 32%, in the case of no coatings, to above 94%.By this, the device cavity surfaces have been protected. The laser output power and working lifetime have been enhanced. |
