have long-pulse durations due to their constant low-pulse
profile. These long-pulse durations cause heat conduction in the tissue resulting in wide,
inconsistent, conical-shaped zones of thermal damage. While CW lasers allow for maximum
tissue involvement, they offer the least amount of consistency and patient comfort.
, has high-peak
power with short-pulse durations, providing more consistent heating within the thermal zone.
The ablation threshold is achieved very quickly and target tissue is ablated with limited thermal
damage, providing increased patient comfort and less downtime.
provides sustainable high-pulse power,
delivering six times more power than most CW lasers. Through extremely short-pulse durations,
UltraPulse ablates tissue very quickly, leaving a narrow, controlled amount of thermal
damage. With 240 watts of average pulse power to tissue, the UltraPulse can ablate deeper
than CW or SuperPulse lasers for indications such as burn scars, while imposing minimal
additional thermal damage.

As pulse widths increase, thermal zones, discomfort and downtime increase.
