[Translate to Chinese:] Phase lock between two lasers showing servo bumps 2.3 MHz away from the carrier signal.
FALC pro
Digitally controlled fast laser locking module
No compromise: Fast and Convenient
- PI³D²调节器
- 10 ns延迟
- 远程锁定
FALC pro是TOPTICA的新一代的锁定模块。其高速调节器甚至可以满足苛刻的应用，包括激光驱动在光学时钟（时钟转换）或量子计算机（光学q位）中使用的超窄跃迁。该调节器与方便的用户界面结合在一起，可以轻松优化反馈参数。模拟调节器的数字控制接口还可以实现完全远程操作。
这种锁定模块的典型应用包括使用外部参考腔缩小激光器的线宽，例如在pound - drevero - hall锁(与PDH/DLC pro结合使用)中，将任何DLC pro控制的TDLS激光器锁在频率梳上，或将一个TDLS激光器锁在另一个TDLS激光器上。
FALC pro和DLC pro Lock的结合增加了更多的便利性，因为点击&锁定以及重新锁定机制都很容易设置。
FALC pro不仅保证了良好的性能，而且在设置反馈以达到很窄的线宽、极低的相位噪声、很长的相干时间……或者只是一个非常好的高速锁方面也很有趣。
