论文摘要
我们报告了激光材料ND：YAG的单晶生长，该应用在应用中通过高级激光光炉中实施的无坩埚浮动区方法广泛使用。我们已经优化了生产激光管典型尺寸的高质量单晶的参数。为了降低应变并提高可加工性，我们开发了一个后卫，以使热区下方的单晶的生长部分热量，这是一种在公共镜炉中无法使用的技术。通过LAUE衍射验证了单晶的高质量，并通过中子衍射记录了内部应变。吸收光谱与Czochralski方法产生的商业使用材料的参数相对应。通过激光加热的浮动区方法对单晶生长的提出的方法适用于制备其他高质量的氧化物基材料的高质量单晶，尤其是在常用的坩埚方法中无法实现的氧化环境中。
We report on single crystal growth of laser material Nd:YAG widely used in the applications by innovative crucible-free floating zone method implemented in an advanced laser optical furnace. We have optimized the parameters for the production of high-quality single crystals of the size typical for laser tubes. To reduce the strain and improve machinability, we have developed an afterheater to thermalize the grown part of a single crystal below the hot zone, which is a technique unavailable in common mirror furnaces. The high quality of the single crystals was verified by Laue diffraction and the internal strain was documented by neutron diffraction. The absorption spectrum corresponds with the parameters of the commercially used material produced by Czochralski method. The presented methodology for the single crystal growth by floating zone method with laser heating is applicable for the preparation of other high-quality single crystals of oxide-based materials, particularly in an oxidizing environment unattainable in commonly used crucible methods.
