Mode-selective toroidal mirrors for unstable resonator planar waveguide and thin slab solid-state lasers [PDF]

, 2009
In this paper, two new fabrication methods are developed for highly curved toroidal laser resonator mirrors based on laser micromachining of cylindrical substrates that already have the large lateral curvature RT provided by conventional polishing. These
