摘要

As the key element of the gyrostats, the single crystal fiber has a wide application in the fields of aerospace, electricity and casting. For the upper limit of the tested temperature is continuously increasing( >2000 t] ) ,a optical system for preparing zirconia crystal optical fiber based on LHPG is proposed, which can prepare the zirconia crystal optical fiber to measure the higher temperature. The basic structure and characteristics of the system are introduced and the parameters of the system are analyzed. The system has been simulated through the ZEMAX optical software. The results show that the system meets the design requirements and it has the advantages of good symmetry, high efficiency, nice uniformity of energy distribution. This provides theoretical basis for the preparation of high temperature zirconium oxide single crystal optical fiber.%单晶光纤是光纤高温传感器的关键器材,在航空航天、电力、铸造等的高温测试领域有着广泛应用.随着温度测试上限要求的不断提高(＞ 2000℃),常用的蓝宝石光纤高温传感器已无法满足该需求.本文针对这一现状,提出了一种基于LHPG法制备氧化锆单晶光纤的光学系统,旨在拉制出能测量更高温度的氧化锆单晶光纤,文章分析了该系统的基本结构、特点以及系统中主要参数的选择设置,并通过ZEMAX光学软件进行仿真.结果表明,该系统能够形成高质量的聚焦光斑,且具有对称性好、激光利用率高、能量分布均匀等优点,为成功拉制氧化锆及更高温单晶光纤提供了理论依据.
