This paper reports the spectral,lasing characteristics of R560 using a XeCl excimear laser,a YAG:Nd laser as pump sources. R560 is one of the Rhodamines synthesized by this group. In our experiments a diffraction grating is used in the dye laser resonator as frequency selection element, which is at grazing incidence in order to minimize the line-width. In this way, we have obtained a linewidth of about 0.1 A. As it has good spectral characteristics, such dye can be used in practical lasers.
