We conducted high-precision measurements of the wavelength of a $4d{^{1}S_{0}}\rightarrow 4p{^{1}P_{1}}$ line of a nickel-like silver X-ray laser. The Lyman series lines of hydrogen-like helium ions emitted from low-density plasmas were used as wavelength references, and the wavelength of the X-ray laser line was determined to be 13.887 nm ($\pm 0.002$ nm). The experimental results were compared with Multiconfiguration Dirac–Fock calculations and were found to agree with theoretical wavelengths.
