我们展示了无限的偏振稳定与控制速度高达9 krad/s，随机庞加莱球轨迹。它们的总长度>35 Mrad，特别是由具有所有半径和方向的难以跟踪的圆组成，因此包括所有可能的最差情况。最大偏振失配和相对强度误差分别为0.13rad和0.43%。该控制器运行在一个现场可编程门阵列，并使用商业多级铌酸锂极化Transformer作为控制设备。
We demonstrate endless polarization stabilization with a control speed of up to 9 krad/s, over random Poincare sphere trajectories. These are in total >35 Mrad long, are composed in particular of difficult-to-track circles with all radii and orientations, and thereby include all possible worst cases. The maximum polarization mismatch and relative intensity errors are 0.13 rad and 0.43%, respectively. The controller runs on a field-programmable gate array and uses a commercial multistage LiNbO3 polarization transformer as the control device.
