Abstract

Radiation from the Ne-like Zn soft x-ray laser (λ=21.2 nm, τ< 100 ps) driven by PALS (Prague Asterix Laser System) was successfully focused with a spherical Si/Mo multilayer-coated mirror to ablate poly(methyl methacrylate), monocrystalline silicon, and amorphous carbon. To our knowledge, this was the first observation of material ablation with a laser working in the soft x-ray region, i.e. λ<30 nm.
