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 .LAMBDA., V, .XI. type three levels. In the .LAMBDA. 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 .XI. 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.

摘要： A method of recording information in an optical recording medium, which comprises two steps. In the first step, a coherent light pulse train which resonates with a transition between the first and third energy levels and coherent light which resonates with a transition between the second and third energy levels or a transition between the first and second energy levels are applied to the optical recording medium, thereby causing the light pulse train to pass through the optical recording medium. In the second step, an intensity change of an external field is supplied to the medium, while the light pulse train is passing through the optical recording medium, thereby fixing sites in a thickness direction of the medium, at which the absorption spectrum of the medium is changed.

摘要： An operating method for stimulated Raman adiabatic passage to change probability amplitude in a three-level system including states of |0>, |1> and |e>, includes the following two steps. One is to direct a first laser beam and a second laser beam which have frequencies in the vicinity of resonance frequencies corresponding to energy differences between |0> and |e> and between |1> and |e>, respectively. The other is to change temporally two-photon detuning to be a difference between first detuning and second detuning. The first detuning is a difference between a first energy difference and a frequency of the first laser beam. The first energy difference is a difference between energy of |0> and energy of |e>. The second detuning is a difference between a second energy difference and a frequency of the second laser beam. The second energy difference is a difference between energy of |1> and energy of |e>.
