| Abstract: | We have studied theoretically and technology process of ZrO2 MgF2, evaporation experimen-tally the coating characteristics viathe plating on the back cavity surfaces of GaAs/GaAlAs laser. Thereflective coefficient have been changed from 32%, in the case without coating, to above 92%. Bythis, the device cavith surfaces have been protected, the output pawer increased, the lifetime extended,and threshold current reduced. |
