摘要

The arrangement has a semiconductor laser (1) for emitting pump radiations (6) for pumping an optically pumped laser (2), which is a solid state laser. The semiconductor laser has a set of monolithically integrated active regions (3-5), which are arranged on top of each other. Two of the active regions emit pump radiations of different wave lengths for optically pumping different absorption bands of an active medium (7) of the optically pumped laser. The semiconductor laser has a resonator, whose length ranges from 0.3 millimeter (mm) to 10 mm.
