Possibilities of observing single mode and intermodal quantum correlations (e.g., antibunching, steering and entanglement) are studied for a probed-hyper-Raman system. The physical system studied here considers that a probe interacts continuously with the non-degenerate pump modes in the hyper-Raman active system via a nonlinear coupling. Using the dynamics of the system in a complete quantum treatment, the impact of the probe on the single and multi-mode quantum correlations generated in a hyper-Raman active system is studied. The investigation has revealed that quantum correlations in the hyper-Raman systems can be controlled using the probe. Specifically, the quantum steering between the pump and anti-Stokes modes can be influenced significantly by controlling the interaction between the system and the probe. Unlike steering, probe could neither deteriorate the nonclassical correlations, namely intermodal entanglement and photon antibunching, nor induce them.
