the power of the pulse

Standard CW lasers 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.

AcuPulse, a more advanced SuperPulse laser, 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.

The premium UltraPulse laser 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.
