Paper Abstract

The results of investigation of interaction of YAG:Ho laser radiation with soft tissue in contact and non-contact modes of processing under fiber-optical delivery system application are presented. The laser wound is evaluated according to the criteria of efficiency (energy of laser radiation spent to removal of unit volume of tissue) and invasion (ratio of irreversibly necrotized tissue volume to removed tissue volume). The dependencies of destruction efficiency index and laser wound invasion on energetical parameters of laser radiation and destruction rate are presented. The considerable difference of destruction efficiencies of contact and non-contact modes is shown. The requirements for optimum parameters of Ho- laser for surgery are formulated.
