Abstract
The successful laser ablation of clinically relevant tissue models by means of picosecond laser pulses is presented. This is a potential alternative to overcome limitations of conventional electrocautery tools in terms of precision and thermal damage. The correlation of high-speed imaging of the process and a histopathological analysis of the post-process tissue morphology enables optimisation of the tissue removal rate whilst avoiding adverse cavitation effects in order to keep the collateral thermal damage to a minimum. Effective tissue removal is presented for the epithelial laser ablation of colonic tissue and the translation of this process towards head and neck surgery and brain surgery is discussed.
