Emission of muonium ($mu^+e^-$) atoms from a laser-processed aerogel surface into vacuum was studied for the first time. Laser ablation was used to create hole-like regions with diameter of about 270$~mu$m in a triangular pattern with hole separation in the range of 300--500$~mu$m. The emission probability for the laser-processed aerogel sample is at least eight times higher than for a uniform one.
