High-bandwidth PID control stabilizes the laser frequency with high precision. A high-speed feedback controller that achieves laser locking and narrow linewidth.
Ultra-fast feedback control for wideband laser stabilization. The FSC is a high-bandwidth PID servo controller designed for precise laser locking and narrowing of linewidth. By separating high-speed and low-speed loops in the feedback control, it achieves high-precision stabilization of laser frequency. Furthermore, its design emphasizes intuitive operability, allowing for rapid optimization of feedback parameters from the front panel, making it ideal for demanding stabilization applications.
