Paper Abstract

The surface temperature behavior as a function of time of water and tissue phantoms irradiated with non-ablative CO2 laser pulses (2 ms) is measured. The temperature decay is very slow and the temperature increase due to the pulse is still non-zero at 70 ms after the pulse is terminated. The slow decay results in accumulation of temperature after multiple pulses at 10 Hz. The thermal behavior suggests that to avoid temperature accumulation when applying (super) pulsed CO2 irradiation, repetition rates must be smaller than 10 Hz.
