Times Cited Count:61 Percentile:89.32(Optics)We demonstrate a generation of highly coherent X-ray laser at 13.9 nm by oscillator-amplifier configuration with two targets. In the oscillator-amplifier configuration, the seeding X-ray laser beam from the first target is injected into the plasma amplifier at the second target. When the X-ray laser beam is not affected by refraction during propagation in the amplifier, the X-ray laser beam with small divergence and high coherence is generated. The observed X-ray laser beam has 0.2 mrad of the diffraction limited divergence and the full spatial coherence.
