Abstract
A pumped laser arrangement comprises a pumping laser and at least first and second laser elements positioned such that their axes intersect at a predetermined angle. A mirror which transmits light emitted by the pumping laser and reflects light emitted by the laser elements is positioned at the intersection of the axes to reflect light between the ends of the first and second laser elements. The pumping laser is optically coupled through the mirror to the end of one of the first and second laser elements.
