Damage thresholds (ED50) for skin using Yucatan mini-pig (Sus scrofa domestica) have been determined at the operational wavelength of 1.3 um with beam diameters of 0.61 cm and 0.95 cm. Exposure durations of 0.25, 1.0, 2.5 and 10 seconds were used to determine trends in damage threshold with respect to exposure time and beam diameter at this moderately penetrating wavelength. A relatively narrow range of total radiant exposure from 19.3 J/cm2 to 30.5 J/cm2 was observed for threshold damage with laser parameters encompassing a factor of two in beam area and a factor of forty in exposure duration.
