摘要
Two mirrors comprising a resonator, arranged facing to each other interpose an EIT layer, which is a solid containing an impurity. A controlling light from a controlling light source and a pumping light from a pumping light source enter the EIT layer. A photodiode detects the intensity of an LWI laser light (a signal light outputted from the EIT layer) outputted from one of the mirrors. A filter for cutting the controlling light is provided between the photodiode and the mirror. Two kinds of lights, that is, the controlling light and the pumping light are used in all the &Lgr;, V, &Xgr; type three levels. In the &Lgr; type three levels, the controlling light is used for supposedly exciting between the levels, and the pumping light is used for pumping electrons from the level to the level via the level. In the V type three levels, the controlling light is used for exciting between the levels, and the pumping light is used for pumping electrons from the level to the level via the level. In the &Xgr; type three levels, the controlling light is used for supposedly exciting between the levels, and the pumping light is used for pumping electrons from the level to the level via the level.
