Abstract
A laser may comprise a ceramic core that at least partially defines a waveguide slab laser cavity. An interior surface of the waveguide slab laser cavity is coated with a layer of metal. The laser also includes a set of mirrors that form a resonator in the waveguide slab laser cavity. The laser also includes electrodes positioned such that the laser gas contained in the waveguide slab laser cavity is excited when an excitation signal is applied to the electrodes. In other embodiments, the core may be formed from a material other than ceramic. Additionally or alternatively, the layer may be formed from a material other than metal.
