Abstract
An axially optically pumped laser 11 is penetrated coaxially by a target beam .lambda..sub.2. This penetration of the pumped laser occurs via light conductor 2 by means of laser diode 31. The pumped laser 11 can be an erbium--YAG laser. For this purpose, the dispersion, diffraction and reflection of an incoupling optic 12, of laser 11 and a focusing device 13 are suitably matched to each other in order that the pump light .lambda..sub.3, work beam .lambda..sub.1 and target beam .lambda..sub.2 are suitably guided and are suitable for small diameters. The laser arrangement is suitable as a medical device for ears, nose and throat and eyes and can be utilized with an endoscope.
