By a modified two manifold model, we explain the following experimental results performed for the test of the optical Bloch equation on the transition -1/2(4A2)～-1/2(E) of the ruby R1 line. 1)The optical hole width, including that derived from the FID increases linearly with x(Rabi frequency) under the strong excitation condition. 2)The decay of two pulse and rotary photon echo is a single exponential and the decay constant is power independent as is predicted from the ordinal optical Bloch equation. In this theory, a fluctuating local field is not assumed.

High resolution spectroscopy using an FM noise of an amplitude squeezed diode laser is applied to a solid state sample for the first time. The ruby R1 lines are examined and the observed line width of the R1 line;-1/2(4A2)～-1/2(E) is 30 MHz(HWHM), which is limited by the short time laser width. The width of the ruby R2 line 1/2(4A2)～-1/2(A) is wider than 125MHz MH, which is restricted within the band widths of the optical detecter and the amplifier.
