Novel optical technologies for ultrashort pulsed laser surgery

Colorectal cancer is the fourth-most prominent cause of cancer related fatalities across the globe. Conventional electrocautery techniques used in the resection of colon tissue cause a relatively high degree of collateral damage to the healthy tissues bordering the target sites. Ultrafast infrared lasers offer significantly improved localisation in the ablation of such biological tissues arising from a plasma-mediated ablation mechanism. This...
