Multiply folded laser systems
A laser resonator which lengthens the optical path of laser radiation in a laser cavity is described, comprising: a gas medium capable of supporting laser action located within the laser cavity; means for supplying power to the laser cavity; means for removing heat from the laser cavity; a polygonal block in the cavity, the block having at least three outer surfaces, and the block having grid of intersecting waveguide channels formed therin, and reflection means comprising a plurality of mirrors, at least one mirror being located along three of the outer surfaces of the block, the mirrors and the grid cooperating to define a folded optical path within the laser cavity, whereby the folded optical path contains a series of crossing paths within the grid.
