摘要

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 -2.8dB,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.
