Laser-induced glass surface structuring by LIBBH technology

A technology of microrelief formation on the fused silica glass surface by laser induced black body heating is considered. An ytterbium fiber laser and a pressed graphite as an absorbent of laser radiation are used in this technology. The depth of the formed relief depending on the laser interact parameters has been investigated. It is shown that the depth increase linearly with increasing of laser radiation power, pulse duration and number of pulses. Possible mechanisms microrelief formation on the glass surface is discussed.
