摘要

通过对GaAs/GaAlAs激光器谐振腔前、后腔面蒸镀2rO

和ZrO

、MgF

的工艺过程

从理论和实验上分析涂层特性

透射率、反射率分别由无膜时的68%、32%

镀膜后提高到94%、95.0%以上

提高了激光输出功率和工作寿命

保护了器件端面。

Abstract

We have studied theoretically and experimentally the coating characteristics via the tech-nology process of ZrO

and ZrO

、MgF

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.
