At that time, the ability of a normal-mode ruby laser with a 0.5 ms pulse duration was noted to selectively destroy pigmented structures in the skin.1 Although seemingly ironic in hindsight, the field of laser dermatology then shifted to the use of continuous wave modalities such as the carbon dioxide laser (10,600 nm) and the argon laser (418 nm), which were used in a non-selective fashion to treat pigmented lesions. Needless to say, the results were often unpredictable, with complications such as scarring and dyspigmentation.
