The continuous-variable orbital angular momentum squeezed states is a crucial resource in the implementation of quantum precise measurement, super-resolution quantum imaging, and quantum storage. Currently, only the lower-order orbital angular momentum squeezed states can be generated by an optical parametric oscillator. However, the higher-order orbital angular momentum squeezed states are more useful for reliable quantum information processing. Here, we use a vortex plate to generate a series of higher-order orbital angular momentum squeezed states. The measured 20th-order orbital angular momentum squeezing is - 3.5 dB. The method may find important applications in high-dimensional quantum information processing and highcapacity quantum communication networks.
