摘　　要：随着激光器功率的提高,高能激光系统对发射窗口的要求越来越高。镁铝尖晶石(MgAl_(2)O_(4))透明陶瓷具有优异的光学、热学和机械性能,广泛用于红外制导窗口、高马赫航空器整流罩,以及极端环境下的光电设备窗口等,但用于激光发射窗口的相关报道尚不多。本文简要介绍镁铝尖晶石透明陶瓷在激光发射窗口的应用研制现状,针对该应用最为关注的性能,测试了目前用于透明防弹装甲和飞行器窗口的镁铝尖晶石透明陶瓷的吸收系数,分析了双金属醇盐法制备的镁铝尖晶石粉体和用热压结合热等静压工艺制备的镁铝尖晶石透明陶瓷的纯度,探讨了影响陶瓷吸收系数的因素。With the increase of laser power,high-energy laser systems have increasingly demanding requirements for laser exit aperture windows.Magnesium aluminate spinel(MgAl 2O 4)transparent ceramics exhibit excellent optical,thermal,and mechanical properties,making them widely used in infrared guidance windows,high Mach aircraft radomes,and windows for optoelectronic equipment in extreme environments.However,there are relatively few reports on their use as laser exit aperture windows.This article briefly introduces the current state of research and development of magnesium aluminate spinel transparent ceramics for laser exit aperture window applications.Focusing on the most critical performance aspects for this application,the absorption coefficient of magnesium aluminate spinel transparent ceramics currently used in transparent bulletproof armor and aircraft windows are tested.The purity of magnesium aluminate spinel powders prepared by the bimetallic alcoholate method and the magnesium aluminate spinel transparent ceramics produced using hot pressing combined with hot isostatic pressing techniques are analyzed.Furthermore,the factors affecting the absorption coefficient of the ceramics are discussed.
