Paper Abstract

The process of channel formation during hole punching in glass by pulse-periodic radiation of carbon-dioxide laser has been experimentally investigated with due account of modulation of radiation that passed through the keyhole under deep penetration conditions (ratio between hole depth and diameter was 3 divided by 10). The frequencies of keyhole walls vibrations in the course of punching and velocities of channel radius variation have been measured. In the experiment, the phenomenon of periodic structure formation on the channel walls under the action of carbon- dioxide laser pulse-periodic radiation has been revealed.
