PHOTON NOISE SQUEEZING AND ITS PHYSICAL MECHANISM OF A DRIVEN VTYPE THREELEVEL LASER

应用Ｓｃｕｌｙ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。

Abstract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.
