(color online) (a) Transmission signal of probe laser (black solid line: without microwave E-field, red dashed line: with microwave E-field, Δ f P is the AT splitting separation), (b) dependence of AT-splitting separation on the square of power of microwave signal generator in two different vapor cells (black square: cubic cell, red circle: cylinder cell, solid lines: linear fitting results).
