Superpulsed carbon dioxide lasers emit a controlled train of short duration, high-power pulses which minimize the protein coagulation effects of the laser. Very high irradiances can be used with superb control of vaporization without significant peripheral heating. In incisional work, superpulsing permits the surgeon to advance the hand piece as slowly and as accurately as desired, while experiencing a fraction of the necrosis attendant to conventional continuous-wave lasers. In vaporizational applications, target tissue volumes are flash vaporized before significant heat can be transferred to surrounding tissue, promoting faster wound healing and reduced scarring. The superpulse feature may significantly change the way in which the carbon dioxide laser is used in cutaneous surgery.
超脉冲二氧化碳激光发射出一系列受控的短持续时间、高功率脉冲，可将激光的蛋白质凝固效应降至最低。可以使用非常高的辐照度，并对汽化进行极好的控制，而不会产生明显的周边加热。在切割手术中，超脉冲使外科医生能够根据需要尽可能缓慢和精确地推进手持器械，同时所经历的坏死程度仅为传统连续波激光的一小部分。在汽化应用中，目标组织体积在大量热量传递到周围组织之前就被瞬间汽化，从而促进更快的伤口愈合和减少疤痕形成。超脉冲特性可能会显著改变二氧化碳激光在皮肤外科手术中的使用方式。
