Systems and techniques for multilayer electrode assemblies are generally described. In some examples, a multilayer electrode assembly may comprise a first dielectric material. In some examples, the first dielectric material may be shaped so as to form a channel defined by an interior surface. In various examples the multilayer electrode assemblies may comprise a first metal layer disposed adjacent to a first portion of the exterior surface of the first dielectric material. In various further examples, the multilayer electrode assemblies may comprise a second metal layer disposed adjacent to a second portion of the exterior surface of the first dielectric material. In some examples, the first metal layer may be disposed in a first spaced relationship with the second metal layer. In various examples, a substantially uniform electric field may be generated in the channel of the first dielectric material when a voltage is applied to the multilayer electrode assembly.

A system for generating an energy beam based laser includes an apparatus for receiving an energy beam and for generating an energy beam based laser. The apparatus is configurable or controllable for tuning an output wavelength of the laser generated by the apparatus using the energy beam. The apparatus includes a first component for producing a first magnetic field oriented in a first direction and a second component for producing a second magnetic field oriented in a second direction substantially opposite to the first direction. A channel through the apparatus is defined by the first component and the second component through which the energy beam passes to generate the laser at an output of the apparatus. The apparatus is configurable or controllable for modifying at least one of the first magnetic field and the second magnetic field for tuning the output wavelength of the laser.

Laser amplification utilizing plasma confinement of a gas laser gain media is described. The gas laser gain media is compressed into plasma utilizing a self-reinforcing magnetic field referred to a plasma pinch (e.g., a flow stabilized z-pinch). In the pinch, the gas laser gain media is compressed to a high density, which improves the gain of the media. Coherent light is transmitted through the plasma pinch, which is amplified by the plasma pinch.

A laser oscillator which can effectively remove scattered light by a simpler configuration. The laser oscillator comprises an output mirror and a rear mirror which are arranged facing each other and a discharge tube which is arranged between the output mirror and the rear mirror. The discharge tube has a first part which gets larger in inner diameter from a first end part in an axial direction facing the output mirror toward the rear mirror.
