本文介绍一种新的,适用于高功率激光核聚变装置的隔离器.这种高速机械转镜隔离器(通光口径(?)140mm,转速6000rpm.)具有很高的隔离比和很低的插入损耗,还同时具有空间滤波和隔反向激光的功能.对发展这种隔离器需解决的同步问是,作了详细的讨论.测得同步精度优于0.3μs,复原精度优于1".对影响精度的因素作了分析.

A new isolator-high-speed mechanical rotating mirror isolator for high power laserfusion systems, is described in this paper. The isolator has a high isolating ratio and a low insert loss, and it can also acts as spatial filter and backward laser beam isolator. The problem of synchnization is investigated in detail. Our experiment shows that an isolator with a beam aperture of 40mm, and a rotative velocity of 6000rpm can achieve a timing accuracy of better than 0.3μs, and a restoring accuracy of better than 0.3 μs，and a restoring accuracy of better than 1". The factors affecting the accuracy are analyzed and methods of improvment are given.
