Up-conversion detection of mid-infrared light carrying orbital angular momentum
文献摘要:
Frequency up-conversion is an effective method of mid-infrared(MIR)detection by converting long-wavelength pho-tons to the visible domain,where efficient detectors are readily available.Here,we generate MIR light carrying orbital angular momentum(OAM)from a difference frequency generation process and perform up-conversion on it via sum fre-quency conversion in a bulk quasi-phase-matching crystal.The maximum quantum conversion efficiencies from MIR to visible are 34.0%,10.4%,and 3.5%for light with topological charges of 0,1,and 2,respectively,achieved by utilizing an optimized strong pump light.We also verify the OAM conservation with a specially designed interferometer,and the results agree well with the numerical simulations.Our study opens up the possibilities for generating,manipulating,and detecting MIR light that carries OAM,and will have great potential for optical communications and remote sensing in the MIR regime.
