Abstract We experimentally demonstrate that HG01 (Hermit–Gauss) and HG10 squeezed states can be generated simultaneously in an optical parametric amplifier. The HG01 mode is a bright squeezed state and the HG10 mode is a vacuum squeezed state. The squeezing of the HG01 mode is -2.8 dB, and the squeezing of the HG10 mode is -1.6 dB. We also demonstrate that the output field is also continuous-variable entanglement with orbital angular momentum.
