Comparisons of the skin damage thresholds for lesions 1 h after exposure, between this work and the work of Oliver et al.³⁹ Oliver et al. presented the damage thresholds for exposure durations of 0.25, 1.0, 2.5, and 10.0 s with the $1/e^2$ spot diameters of 0.61 and 0.97 cm, respectively. This work determined the damage thresholds for exposure durations of 0.4, 1.0, and 3.0 s with the $1/e^2$ spot diameter of 0.98 cm, and for exposure duration of 3.0 s with the $1/e^2$ spot diameter of 1.96 cm, respectively.
