The configuration and operational characteristics of a novel distributed feedback dye laser utilizing layers of small gel particles are investigated and discussed in this paper. The distributed feedback is provided by periodic corrugation of small OH-gel particles, the diameters of which are about 5 μm, placed on the bottom of the dye cell. Using Rhodamine 6G in methanol solution, output beam patern from the dye laser incorporating layers of OH-gel particles was effectively improved compared to the case without the layers. The lasing spectral width for this new structure laser is observed to be 0.63_??_0.85 nm. The considerably narrowed line width along with the improved beam pattern demonstrates the distributed feedbac effect caused by the layers of small gel particls in the dye cell.
