| Abstract: | We have studied theoretically and experimentally the coating characteristics via the tech-nology process of ZrO2 and ZrO2、MgF2 evaporation plating an the front and back cavity Sur-faces of Ga As/GaAlAs Laser.The transmission coefficient and reflective coefficient havebeen changed respectively from 68% and 32%,in the case without coatings,to above 94%and 95%. By this,the device cavity Surfaces have been protected,the out put power in-creased,and lifetime extended. |
