[Experimental study of ablation effect on canine esophagus irradiated by pulsed Ho:YAG laser].

To evaluate the influence of power, irradiation time, energy of per pulse and frequency on ablation effect of pulsed Ho:YAG laser, five canine esophagi were studied. We irradiated the mucosa in different power and different irradiation time. For the same power, the samples were divided into two groups: the high energy per pulse low frequency (H)group and… CONTINUE READING
