OPTICALLY PUMPED magnetic sensor AND MAGNETIC measuring METHOD

The present invention provides an optically pumped magnetic sensor capable of expanding a measurable magnetic frequency band. The optically pumped magnetic sensor is provided with: a cell filled with an alkali metal; a pump light source that generates a pump light; a probe light source that generates a probe light; a signal output unit that obtains an output signal related to magnetism, which is received by the cell, based on the probe light which has passed through the cell; a coil unit that generates a static magnetic field along a pump optical axis in a region of disposition of the cell; and a computer that controls operation of the coil unit. The computer outputs a first control signal to set an intensity of the static magnetic field to a first intensity, and a second control signal to set the intensity of the static magnetic field to a second intensity different from the first intensity. 本发明提供能够扩大可测定的磁力频段的光激发磁传感器，其具备：封入有碱金属的容器；产生泵浦光的泵浦光源；产生探测光的探测光源；基于通过容器之后的探测光，得到与容器接受到的磁力相关的输出信号的信号输出单元；使容器的配置区域产生沿着泵浦光轴的
