Abstract

Optically pumped laser wherein the light beam P, which comes, for example, via light conductors 4 from the pump light source 200, is split into two component beams (T1, T2), for example, by a beam splitter 2. The two component beams (T1, T2) are directed to the laser medium 1 separately, for example, from both ends, or at an angle onto one end. Laser crystals such as Nd:YVO.sub.4, Nd:YLF, Nd:LSB or Nd:YAP having polarization-dependent absorption are especially suitable for pumping.
