SciDre激光高压光学浮区炉

激光加热高压浮区炉LKZ

我们的激光加热浮区晶体生长炉LKZ的主要部分是5个波长为980 nm的300w二极管激光器。影响样品的激光束的矩形几何形状和尺寸可以在很大范围内改变，以适应不同的样品材料和杆径。除了可配置的激光加热系统，我们的LKZ炉最显著的特点之一是可以在高达300巴的高压下进行激光加热的FZ晶体生长。有LKZ版本的10巴，50巴，150巴和300巴最大。压力可用。过程气氛的组成和压力可以通过每个气体的独立质量流量控制器和易于自动化的压力调节器进行精确调节和控制。这种世界范围内独特的设置允许用户将熔体和大气之间的元素扩散控制到一定的等级，并管理材料的生长，由于其元素的高挥发性或所需相的亚稳定性质，在低气压下难以或不可能生产。我们专利的基于激光的后加热器系统为对样品进行额外的热处理提供了无与伦比的灵活性。真空涡轮泵直接连接到工艺室使用短和宽直径的管道。这确保了过程室内的良好真空，即使低于10-5毫巴也是可能的。为了进行超清洁生长，许多过程需要具有低氧分压的惰性气氛。我们可选的气体清洗系统可可靠地去除氩气中的氧气痕迹，残余O2浓度可降至10-12 ppm。此外，可以用高质量的双色高温计测量浮区以及进料和结晶棒的温度。所有熔炉都配备了精确的线性和旋转进料系统，用于同步或独立旋转，转速可达50转/分钟，线性拉出速率从0.1甚至0.01毫米/小时开始。一个快速齿轮是实现杆设置。高压驱动器是磁耦合的，完全封装，没有加压轴承。整套实验参数，如激光功率，拖动驱动器的直线和旋转运动，质量流量和气体压力由可编程逻辑控制器PLC控制。一个舒适的软件应用程序显示和直观地操作通过触摸屏结合所有相关的系统信息和过程调整在一个图形用户界面单元。LKZ系统的一个重要特点是易于扩展的模块化设计，它允许以一种简单且经济高效的方式进行附加和升级。
