A Laser-Driven Neutron Source (LDNS) is a novel neutron that provides neutron beam of ultra-short pulse duration and high flux. This technique would be useful for neutron resonance non-destructive diagnosis application. A demonstration experiment was carried out using an LDNS developed for the LFEX laser of Institute of Laser Engineering, Osaka University. A neutron resonance spectrum was observed with a single laser shot. The technique can be used as a "nuclear thermometer" because the resonance shape is broadened as a function of the sample material temperature.
