Saturated and near-diffraction-limited operation of an XUV laser at 23.6 nm
Amplification of spontaneous emission (ASE) at 23.6 nm has been studied in a Ge plasma heated by a 1 TW infrared laser pulse. The exponent of the axial gain reached 21 in a geometry with Fresnel number ≤ 1. Two plasma columns of combined length up to 36 mm were used with an extreme ultraviolet mirro...
