Abstract
In a high power laser the optical resonator elements, such as reflectors for the optical resonator and optical pump are supported in optical alignment from a structural beam of generally L-shaped cross section and made of high thermal conductivity material such as copper or aluminum via the intermediary of a plurality of longitudinally directed rods made of a low thermal expansion material such as quartz or Invar. The rods are supported at one end from the L-shaped beam via leaf springs and they are rigidly coupled to the L-shaped beam at their other ends. The remaining elements such as the optical pump, Q switch and polarizers are supported directly from the L-shaped structural beam.
