| contents | We present, to the best of our knowledge, the first demonstration of an optical spring in a signal-recycled Michelson interferometer without arm cavities. The setup utilizes multiple laser fields to achieve stable and precisely controllable detuning and incorporates a compliant suspension system comprising two double-spiral springs. These results support optical spring-enhanced interferometers with intracavity amplification, offering a promising avenue for improving high-frequency sensitivity in future gravitational-wave detectors. |
