Abstract

A laser system (10) is disclosed comprising a laser device (1) for emitting laser radiation and an optical fibre (2) adapted to connect, in use, to the laser device (1) for delivering the laser radiation. The optical fibre contains a label (3), such as an RF identification tag, a barcode or a colour code. The laser device (1) interrogates the optical fibre (2) and receives information back from the optical fibre (2). If the usage of the optical fibre (2) has exceeded safety limits then the laser device (1) may be prevented from operating. The laser device (1) on receiving information from the optical fibre (2) may also be configured to deliver laser radiation having a specific power, pulse width, pulse interval and treatment duration.
