摘　　要：用矩阵光学理论计算了由主振荡器和功率放大器组成的种子注入光腔。主振荡器光腔是由曲率半径R1=-250mm,R2=5000mm,相距L=2375mm的球面镜组成的正支非稳腔;功率非稳腔是由曲率半径R3=400mm,R4=5600mm,相距S=3000mm的球面镜构成的负支非稳腔。理论计算表明,该种子注入光腔可输出光束发散角约几十微弧的激光,可满足铜蒸气激光器主振荡器功率放大器(MOPA)的技术要求。The characteristics of seed injected oscillator consisting of main oscillator and power amplifier are analyzed by matrix optics theory. The main oscillator consists of two spherica mirrors of curvature -250 mm and 5 000 mm, spaced 2 375 mm apart. The power amplifying cavity consists of two spherica mirrors of curvature 400 mm and 5 600 mm, spaced 3 000 mm apart. The full beam divergence of the oscillator output is about scores of μrad, which can satisfy the requirements of MOPA technology in copper vapor laser. \;
