    Continuous variable squeezed light plays an important role in quantum information processing, and the most effective generation tool known is the optical parametric oscillator. At present, most research focus on the fundamental mode, however, the intensity and phase distribution of higher-order mode are more complicated. In addition, based on the characteristics of different order modes and their orthogonal characteristics, high-order mode squeezed light brings more choices and applications for quantum communication and quantum precision measurement. This review introduces the experimental research progress of the continuous variable higher-order mode squeezed light based on the optical parametric oscillator, and expounds two common methods for generating high-order mode squeezed light field, including operation in high-order mode OPO and fundamental mode squeezed light combined mode shaping device.
