PROBLEM TO BE SOLVED: To provide a color element laser amplification device which can efficiently amplify laser light. SOLUTION: In a color element laser device, color element cells where flow passages 9a in which color element solution circulates are formed are installed and color element solution circulating the flow channels is excited by exciting light P from a direction crossing the circulating direction. An exciting light source 11 generating exciting light, a division mirror 12 dividing exciting light P from the exciting light source 11 into a plurality of divided exciting light beams P1 -P4 , a plurality of optical fibers 14a-14d which have incident ends and outgoing ends and on which divided exciting light beams are made incident from the incident ends and cylindrical lenses 15a and 15b, which converge the divided exciting light beams emitted from the outgoing ends of more than two optical fibers among a plurality of optical fibers to be long along the flowing direction of color element solution flowing in the flow channel of one color element cell, and which radiate color element solution, are installed. |
