A mathematical model is constructed to describe the formation of inhomogeneous surface structures 10-50 {mu}m in height on metal surfaces exposed to repetitive laser pulses with the following parameters: pulse duration of {approx}20 ns, pulse repetition rate of {approx}10 kHz, pulse intensity in the range 10{sup 7}-10{sup 8} W cm{sup -2} and beam diameter from 50 to 100 {mu}m. The model takes into account melting of the metal and melt flow over a distorted surface. The surface profile amplitude evaluated in the model agrees with experimental data.
