摘要
调制转移光谱技术广泛应用于高精度激光稳频，而调制边带的非对称性会引起调制转移光谱谱线中心过零点的频移，从而影响稳频的长期稳定性及复现性．从密度矩阵运动方程出发，导出非对称边带的调制转移光谱线型公式．以此线型公式为基础，从理论上举例讨论了几种因素对稳频的影响，并模拟计算了谱线中心频移与边带非对称程度的关系．
Modulation Transfer Spectroscopy (MTS) has been proved to be a very effective method in laser stabilization.The asymmetric sidebands shift the line center of the MTS spectrum,and then reduce the long term stability and reproducity of laser frequency.In this paper the formula for the line shape of MTS is derived based on the density matrix equations.The formula is applied for the calculation of either the symmetric or asymmetric sidebands.Using this formula,the frequency shift due to the asymmetricity of the sidebands is estimated.
