PURPOSE:To sensitively prevent the dimerization of fluorescent dye molecule in a wide range when water is used as solvent, by forming a dye laser element by using water-containing solution of enclosure compound wherein fluorescent dye is included in at least one kind of nucleic acid derivatives having cholic acid salt and purine base. CONSTITUTION:An excitation light source makes a dye laser element oscillate, by inducing stimulated emission of fluorescence of fluorescent dye of the dye laser element. This dye laser element is composed of water-containing solution of inclusion compound wherein fluorescent dye is included in at least one kind of nucleic acid derivatives having cholic acid salt and purine base. When water is used as solvent, the dimerization of fluorescent dye molecule is sensitively prevented, the decrease of laser oscillation output is prevented, the optical discoloration of fluorescent dye molecule is restrained, and the dye laser of long life can be obtained. |
