应用Scully-Lamb理论研究受驱动V型三能级激光的光子噪声压缩及其物理机制.结果表明该系统可达到10%的腔内压缩和近20%的腔外压缩.尽管V型系统的噪声压缩程度远比Λ型系统(近50%的腔内和腔外压缩)低,V型系统具有与Λ型系统相同的噪声压缩机制.Photon noise squeezing and its physical mechanism of a driven V-type three-level laser are investigated via Scully-Lamb theory.It is shown that intracavity squeezing of 10% and extracavity squeezing of 20% can be achieved.Even if the amount of squeezing in V system is smaller than that in Λ system (intracavity squeezing and extracavity squeezing of up to 50%),both systems have the same mechanism responsible for the squeezing of photon noise.
