Abstract

In vitro perforation of gelatin-based biomodels and myocardium tissue by powerful CO₂ and YAG:Er laser pulses is considered. Features of the thermal and shock-wave effects on the walls of the laser channel are investigated. Patterns of laser channeling in gelatin by a single YAG:Er laser pulse were studied.
