(a) Temperature increase per averaged power at OFD for three different intensity thresholds (532 nm; 10, 5, and 1.3 mW/mm²). Dashed and solid lines represent 30% and 50% duty cycles, respectively. (b) A rate of temperature changes per averaged power at OFD as a function of the threshold criterion for different duty cycles (30% and 50%). The temperature change at OFD for 549 nm light are in the ranging from 0.0526 °C/mW to 0.0733 °C/mW (mean = 0.064 °C/mW, standard deviation σ = 0.0054).
