摘要
理论分析了当抽运激光具有高于标准量子极限的经典噪声时,在单共振条件下,由倍频腔输出的532 nm 绿光光场的强度噪声起伏,并从实验上获得稳定的强度噪声低于散粒噪声极限的绿光压缩光,实测的绿光最高强度噪声压缩度为20% ( 考虑到探测器效率及光路损耗,实际压缩度达30% ) .
Considering the noise characteristics of the pump source,the noise spectra of output harmonic field from the singly resonant frequency doubler is derived by means of the motion equations for SHG.The intensity noise squeezing of 20% has been measured from the stable SH wave output.(It is in accordence with the squeezing of 30% if the efficiency of detection system is taken into account).The maximum squeezing measured experimentally is in agreement with the theoretical predictions.
