Abstract

We report what is to our knowledge the first experimental study of beam quality and prepulse effect for a deeply saturated neonlike Zn soft-x-ray laser at 21.2 nm, comparing two distinct regimes of operation: amplified spontaneous emission (in single pass) and double pass. The single-pass x-ray laser output emitted by a 30-mm-long plasma column delivers a smooth, highly symmetric ellipsoidal beam with horizontal and vertical divergence of 3(±0.5) and 5(±0.5) mrad, respectively. With a half-cavity consisting of a Mo:Si flat multilayer mirror, the x-ray laser output is boosted by factor of ∼11, providing a narrowly collimated beam with horizontal and vertical divergence of 3.8(±0.5) and 5.8(±0.5) mrad, respectively. The dependence of the beam parameters on the half-cavity setup and on the level of prepulse is described and discussed.
