The effect of the random phase noise on the contrast is analyzed using the experimental observation of the contrast in the J-KAREN laser. The random phase noise can be a good explanation for the pedestal observed in our contrast measurement. Thus, we concluded that the spectral phase noise generated in the grating in a compressor is the most probable factor causing the pedestal.
