Abstract

The use of lasers in neurosurgery requires irradiation protocols leading to efficient tissue ablation with minimal peripheral damage.1 It has long been recognized that laser power, pulse duration, and wavelength affect the efficiency of tissue removal. More recently, it has been suggested that pulsed lasers would be less injurious to peripheral tissue, provided the pulse could be made shorter than the characteristic thermal diffusion time from the point of laser application.2 However, pulse repetition frequency will also dearly affect the transport of heat away from the ablation cavity.
