A laser system 10 has a laser source 11 which is arranged to emit a high power parallel laser light beam along an optical axis 12 concentric with a socket which is designed slidingly to receive a laser launch system 20. The system 20 includes a focussing lens, is replaceably secured to the socket by means of a spring loaded latch 21, and is arranged to receive a fibre delivery system 25 having a single optical fibre along which focussed laser radiation is directed. Source 11 is controlled in wavelength and power output by a switching arrangement 44 actuated by actuator 45 which carry coded information concerning the particular optical configuration of the systems 20, 25.
