We have designed, constructed, and tested an x-ray laser resonator operating in the hard x-ray, keV energy region. This ring x-ray laser cavity is formed by four highly oriented pyrolytic graphite crystals. The crystals are set at the Bragg angles that allow for the complete 360 degrees round trip of the 2.37 angstrom, 5.23 keV L-alpha line of neodymium. In addition, we also present experimental data of a similar ring laser resonator that utilizes the Cr K-alpha, 5.41 keV, x-ray line to propagate through the four mirrors of the cavity. The specific properties of these x-ray laser resonator mirrors, including reflection losses and cavity arrangement, are presented.
