Abstract  A scheme of quantum nondemolition measurement of transverse optical phonons in a Raman crystal is presented through detecting an anti-Stokes field. The exact solutions of the system is obtained. According to the calculation of the criteria for quantum nondemolition measurements, it is shown that under certain conditions the amplitude quadrature component of the phonon mode can be measured without demolition by the phase quadrature component of the anti-Stokes mode.
