Welding by thulium laser system: tensile strength tests

Abstract

Laser tissue welding tensile strength tests were performed on Wistar rat skin by using diode-pumped and fiber-coupled Thulium (Tm:YAP) laser system emitting at 1980-nm, which is developed for medical applications. The success of laser tissue welding at 100 mW and 5 s in both continuous wave and modulated operation modes were compared with the results by suture technique. Tm:YAP laser at 100 mW, 5 second (34,66 W/cm2) was found successful for tissue welding studies.
