为了确定产生圆偏振X射线激光所需的磁场强度，我们尝试了通过使用高分辨率光谱仪对类镍钼X射线激光的光谱宽度（λ = 18.895 nm）进行首次测量。在实际激光条件下测得的光谱宽度为Δ λ = 18 μ m埃。产生圆偏振X射线激光所需的磁场为40 T。在15 T外磁场下清楚地获得了X射线激光线的分裂。与外部磁场相比，从X射线激光线的分裂估计的磁场的强度是大的。这意味着增益介质等离子体中可能存在另一种增强磁场的机制。
We attempted the first measurement of the spectral width of the nickel-like molybdenum x-ray laser (lambda = 18.895 nm) 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 Delta lambda = 18 m angstrom 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.
