The interaction of the near IR femtosecond laser pulses with photochromic glass sample is investigated. Two different types of microstructures due to the optical properties modification of the sample are observed at the irradiated regions with single laser pulses. Laser fluence and shot number dependency of the structures are investigated. The optical transmission of irradiated areas is analyzed spectroscopically.
