Abstract

There is provided an optical nuclear magnetic resonance device capable of shaping the spatial distribution of the intensity of a laser applied to a diamond (sensor material) from a gaussian shape into a spatially-uniform top-hat shape for shortening the time period necessary for initialization, thereby shortening the measurement time period. The optical nuclear magnetic resonance device 1 includes: a sensor material 101 containing an electron spin that induces electron spin resonance; a laser 102 that the sensor material 101 controls an orientation of the electron spin on a defect contained in the sensor material 101 and measures the orientation of the electron spin; a beam shaping element 105 that controls the laser; a detecting unit that measures a fluorescence emitted from the sensor material due to the laser 102 applied thereto; a microwave irradiation device 103 that applies a microwave to the sensor material 101; a permanent magnet or electromagnet 106 that applies a static magnetic field to the sensor material 101; and a control unit 108 that controls the laser 102, the microwave irradiation device 103, and the beam shaping element 105 so as to uniformize a two-dimensional intensity distribution of the laser 102.
