We experimentally demonstrated the quantum anticorrelation between fundamental ( 1064 nm ) and second-harmonic ( 532 nm ) fields in an external cavity-enhanced singly resonant periodically poled KTP (PPKTP) frequency doubler. Fundamental amplitude squeezing of 0.5 dB and second-harmonic amplitude squeezing of 0.3 dB were generated simultaneously at a pump power of 6.1 mW . Meanwhile, quantum anticorrelation of 0.64 dB between the squeezed fundamental and the second-harmonic fields was observed.
