Abstract :
A study was made of the dynamics of craters growth when a millisecond light pulse with a complex temporal profile interacted with the surfaces of transparent insulator when plasma formed on the both sides of the irradiated sample. The effective growth of craters was found to last no more than 100 mus and it consisted of two stages. In the first stage the area of the damage region increased while its depth remained practically constant, whereas in the second stage the crater growth was three-dimensional
