利用周期性极化KTP外腔谐振倍频过程实现明亮振幅压缩光
Bright Quadrature Amplitude Squeezed Light from Periodically Poled KTP Second Harmonic Generation
摘要
利用自制的单频连续Nd∶YVO4激光器输出的1064nm激光作为抽运源，通过周期性极化KTP晶体外腔倍频过程实现了倍频绿光的正交振幅压缩，并研究了绿光压缩度对抽运光功率的依赖关系，当抽运光功率为59 mW时，实验中观察到压缩度为0．6 dB(考虑到探测效率，实际压缩度为1．1 dB)的明亮绿光振幅压缩光，实验结果与理论预测基本一致。
Abstract
The authors realize the experimental observation of green bright quadrature amplitude squeezed light through a home-made 1064nm single-frequency Nd ∶ YVO4 laser doubled in a periodically poled KTP crystal inside a standing-wave cavity. The squeezing as a function of input power is investigated. When the pump power is 59 mW,the result is we observed 0.6 dB second harmonic squeezing. The experimental results agree with the theoretical predictions.
