极低的噪音和的控制
方便的本地和远程操作
智能锁定功能
DLC pro是一个平台，可驱动TOPTICA的所有可调二极管激光器：适用于所有波长的控制器。
二极管激光器的性能在很大程度上取决于其控制器DLC pro是一个基于数字基础的二极管激光控制器，DLC pro是一个基于数字基础的二极管激光控制器，它对获得所有关键参数的优良性能至关重要:窄激光线宽的低电流噪声，稳定运行的出色的温度控制和频率调谐的压电控制。
为了释放此高性能控制器的全部潜能，提供了直观的用户界面：借助触摸屏和旋钮，可以轻松调整扫描，放大观察到的功能，激活频率锁定等。数字基础还可以实现全面的远程控制，包括Windows计算机的GUI和命令界面。该接口对所有编程语言开放；提供了Python SDK。
许多应用需要参考激光的频率。 TOPTICA提供满足所有需求的解决方案：便捷的软件解决方案DLC pro Lock直接集成到DLC pro中，而FALC pro提供了高性能锁定。
DLC pro是二极管激光控制器的基准：具有优良性能的硬件，以以前没有的便利性运行。
Python 支持 | 作为TOPTICA的Laser SDK的一部分，我们提供了DLC pro的Python支持，可通过pip安装轻松获得。 该软件包又Python软件包索引（PyPI）提供。 |
