Power recycling is a technique used in interferometry that enhances the sensitivity of measurements by reflecting light back into the optical cavity, effectively increasing the power of the light being used in experiments. This method allows for improved signal-to-noise ratios, making it crucial for precise measurements in various applications such as gravitational wave detection and laser stabilization. By utilizing power recycling, the overall efficiency of interferometric systems is significantly boosted.
