Abstract
A gravitational-wave detector in space can register signals in the low-frequency band below 1 Hz. The signal laser from a remote satellite has a typical power of only several picowatts, which hinders precise detection of the laser's phase. With this in mind, the authors present an ultranarrow-band amplifier with high gain and low noise, which exploits four-wave mixing induced by radiation pressure. This mechanically mediated amplifier can work at the quantum noise limit, in principle. Moreover, this approach may allow one to generate quantum entanglement between the amplified and conjugate fields.
