An optical pumping magnetometer measures a magnetic field of a measurement object using optical pumping. The optical pumping magnetometer includes a nonmagnetic cell in which at least an alkali metal is enclosed and which has optical transparency and heat resistance, a laser beam irradiation unit which radiates a laser beam to the cell and optically pumps at least the alkali metal, a detecting unit which receives a transmission laser beam transmitted through the cell and detects a detection signal related to the magnetic field, and a high frequency voltage applying unit which applies a high frequency voltage to a pair of application units provided on the cell and heats the cell by dielectric heating.一種光泵磁強計,乃是利用光泵對測量對象的磁場進行測量之光泵磁強計;其具備有:非磁性槽,至少封入鹼金屬且具有透光性及耐熱性;雷射照射部,將雷射照射於前述槽,並至少進行前述鹼金屬的光泵激;檢測部,接收透射過前述槽之透射雷射,並檢測有關前述磁場之檢測信號;以及,高頻電壓施加部,對設置於前述槽之一對施加部施加高頻電壓,並藉由介電加熱對前述槽進行加熱。1‧‧‧光泵磁強計2‧‧‧玻璃槽(槽)2a‧‧‧內部空間3‧‧‧雷射光源(雷射照射部)4‧‧‧檢測器(檢測部)4a、4b‧‧‧光接收部5‧‧‧高頻電源(高頻電壓施加部)5a‧‧‧導線6‧‧‧控制器6a‧‧‧控制裝置(控制部)6b‧‧‧記憶裝置7‧‧‧λ(lambda)板(雷射照射部)8‧‧‧半透半反鏡9a、9b、9c‧‧‧反射鏡10‧‧‧鹼金屬11‧‧‧緩衝氣體12a‧‧‧第1電極(施加部)12b‧‧‧第2電極(施加部)13‧‧‧磁屏蔽(外部磁場屏蔽部)14‧‧‧亥姆霍茲線圈(外部磁場屏蔽部)15‧‧‧亥姆霍茲線圈用電源D‧‧‧絕熱材料Da‧‧‧開口部L、L0、L2‧‧‧雷射L1‧‧‧雷射(透射雷射)P‧‧‧磁場源(測量對象)
