Abstract. Results of experiments on the formation of submillimeter-diameter channels with a large aspect ratio (~100) in polymethyl methacrylate due to selected laser beam focusing parameters and the average power of a high-frequency pumped CO laser are presented. A comparative analysis of the possibilities of forming channels in polymethyl methacrylate using radiation from CO and CO2 lasers with high-frequency pumping is performed. Submillimeter channels with high aspect ratio can be used to create microfluidic chips.
