Comparison of Office-based KTP and CO2 Laser Outcomes in Patients With Vocal Cord Lesions.

"the CO2 laser (AcuPulse DUO, Lumenis, Yokneam, Israel) generally ranges from 3 to 10 W in superpulse mode, with 0.05 second on/0.01 second off, depending on lesion size and location of the lesion(s).~The CO2 laser can be used in a continuous, pulsed, or superpulsed mode. The superpulsed mode reduces the exposure time to a few nanoseconds while delivering high energies of 400 to 500 W with each peak. The rest time between each peak allows the tissues to cool and reduces thermal injury to adjacent tissues."
