Brief Communications


A description is given of the damage caused in blocks of PMM by variously focused laser radiation at pulse energies up to 900 J. It is established that in the process of crack formation and development laser radiation is absorbed in the crack. It is suggested that the micropores present in the polymer are centers of crack nucleation.
