Based on the nuclear pumped laser technique, an optical self-powered neutron detector is now being investigated, in the JAERI Advanced Science Research Center. The first experiment has been made using lasing gas cells with three components of He-3 gas (1140 mmHg), Ne gas (588 mmHg) and H2 gas (206 mmHg or 412 mmHg), or Ar gas (206 mmHg) instead of H2 gas in a thermal neutron flux of about 109n/cm2 sec. For this irradiation, optical light of 585.3 nm from the transition of Ne 3P1→3S2 has been observed clearly from those gas cells. The optical light output was increased according to the reactor power and the measurement of the optical attenuation coefficient of 585.3 nm in this gas has been made and is found to decrease for increasing neutron flux. From these results, the nuclear pumped laser can be expected to be in operation above a neutron flux of 1011n/cm2·sec. The second experiment is now under preparation
