Deep Loop Shaping: AI-designed controllers improve LIGO sensitivity
2025-09-18
Our collaboration with Google DeepMind has produced a new reinforcement-learning method called Deep Loop Shaping that designs better feedback controllers for LIGO’s mirror stabilization systems. The technique uses frequency-domain rewards to train controllers that reduce low-frequency control noise by over 30x across the 10–30 Hz band at LIGO Livingston — surpassing the quantum-noise-limited design goal.
DOE INFUSE award for optical cavity research with Blue Laser Fusion
2024-09-19
Our group has been awarded a DOE INFUSE project in collaboration with Blue Laser Fusion, a startup founded by Nobel laureate Shuji Nakamura. The project applies optical enhancement cavity technology — originally developed for LIGO gravitational-wave detectors — to high-repetition-rate pulsed laser systems for inertial fusion energy.
