Abstract: We have developed a novel technique for the measurement of the avalanche fluctuation of gaseous detectors using a UV laser. The technique is simple and requires a short data-taking time of about ten minutes. Furthermore, it is applicable for relatively low gas gains. Our experimental setup as well as the measurement principle, and the results obtained with a stack of Gas Electron Multipliers (GEMs) operated in several gas mixtures are presented.<br />Comment: A supplemental material (Addendum to be published in Nucl. Instrum. Methods Phys. Res. A) was added at the end of the manuscript. 8 pages, including 7 figures
