摘要
利用输出波长为1.3 μm的全固态单频红外激光器进行外腔倍频,获得稳定的外腔倍频红光激光输出,产生的红光用来泵浦由Ⅱ类非临界相位匹配的LBO晶体构建的光学参量振荡腔。在光学参量振荡器非简并运转的情况下,观察到了信号光和闲置光的强度差起伏的关联,实测强度差噪声压缩度为3.9 dB。
Abstract
The stable red laser,which is generated by the laser at 1.3 μm wavelength from an all-solid-state single frequency infrared laser pumping a frequency-doubler,is used to pump a continuous wave nondegenerate optical parametric oscillator (cw-NOPO) consisting of LBO crystal with type-Ⅱ non-critical phase matching.The intensity-difference squeezing of 3.9 dB at a telecommunication wavelength has been generated from the cw-NOPO operating above the oscillation threshold through the frequency down-conversion process.
