我们采用开放量子系统的观点来计算原子偶极矩在共振激光驱动下产生的电场的功率谱。这一光谱与通常的Mollow光谱形状相似，但也有一些明显的特征。对于足够强的激光驱动，这两个光谱都具有对称的三重态结构，具有一个大的中心峰和两个边带。然而，边带相对于中心峰值的相对高度在每种情况下都是不同的。当激光拉比频率变化时，这两个光谱的表现也截然不同。这两个光谱可能对原子系统，特别是人造原子的量子物理的高精度实验感兴趣。
We adopt an open quantum systems perspective to calculate the power spectrum associated with the electric field generated by an atomic dipole moment undergoing resonant laser-driving. This spectrum has a similar shape to the usual Mollow spectrum, but also has some distinct features. For sufficiently strong laser driving, both spectra have a symmetric triplet structure with a large central peak and two sidebands. However, the relative height of the sidebands to the central peak differs in each case. The two spectra also behave quite differently when the laser Rabi frequency is varied. Both spectra may be of interest in high-precision experiments into the quantum physics of atomic systems, especially artificial atoms.
