Most studies for postselected weak measurement in optomechanical system focuson using a single photon as a measured system. However, we find that using weakcoherent light instead of a single photon can also amplify the mirror'sposition displacement of one photon. In the WVA regime (Weak ValueAmplification regime), the weak value of one photon can lie outside theeigenvalue spectrum, proportional to the difference of the mirror's positiondisplacement between the successful and failed postselection and its successfulpostselection probability is dependent of the mean photon number of thecoherent light and improved by adjusting it accordingly. Outside the WVAregime, the amplification limit can reach the level of the vacuum fluctuations,and when the mean photon number and the optomechanical coupling parameter areselected appropriately, its successful postselection probability becomeshigher, which is beneficial to observe the maximum amplification value underthe current experimental conditions. This result breaks the constraint that itis difficult to detect outside the WVA regime. This opens up a new regime forthe study of a single photon nonlinearity in optomechanical system.
