A laser chamber may include a first discharge electrode, a second discharge electrode, a fan making a laser gas flow through a discharge space between the first and second discharge electrodes, a first insulating member disposed on upstream side and downstream side of the first discharge electrode in the laser gas flow, a first metal damper member disposed on upstream side of the second discharge electrode and a second insulating member disposed on downstream side of the second discharge electrode in the laser gas flow, and a second metal damper member disposed on downstream side of the second insulating member in the laser gas flow. In a boundary portion between the second metal damper member and the second insulating member, a first discharge space side surface of the second metal damper member may be located further toward the opposite side to the discharge space than a second discharge space side surface of the second insulating member. A first corner formed by the first surface and a first side surface of the second metal damper member, the first side surface being on the side of the second insulating member, may be in contact with a second side surface of the second insulating member, the second side surface being on the side of the second metal damper member.

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 plasma pinch, the gas laser gain media is compressed to a high density, which improves the gain of the media. An optical resonator partially surrounds the plasma pinch and utilizes the laser gain media compressed within the plasma pinch to generate an output of coherent light.
