Abstract
A diode pumped Nd:YAG laser is disclosed. The YAG rod is coated on its ends to define an optical resonator containing the YAG rod. The YAG rod is made sufficiently short, i.e., 1 mm, so that it will support only two axial resonant (lasing) modes. The rod is transversely stressed to polarize the two original modes and to excite a third lasing mode orthogonally polarized to the first two modes. The third mode is separated from the first two modes to provide stable, single mode TEM.sub.001 output. The transverse stress is applied by means of a spring clamp made of a material, Be-Cu, having a low temperature coefficient.
