Abstract

We attempted the first measurement of the spectral width of the nickel-like molybdenum x-ray laser (<TEX>${\lambda}\;=\;18.895\;nm$</TEX>) by use of a high-resolution spectrometer in order to determine the strength of the magnetic field required for the generation of a circularly polarized x-ray laser. The spectral width was measured to be <TEX>${\Delta}{\lambda}\;=\;18\;m{\AA}$</TEX> under the substantial lasing condition. The magnetic field required for the generation of a circularly polarized x-ray laser was 40 T. The splitting of the x-ray laser line was clearly obtained under 15 T external magnetic field. The strength of the magnetic field estimated from the splitting of the x-ray laser line was large compared with the external magnetic field. It implies that there might be an alternative mechanism for enhancement of the magnetic field in the gain medium plasma.
