Beschreibungen/Notizen

• The Ni-like 4{ital d}-4{ital p} laser scheme has been extended to wavelengths near the {ital K} absorption edge of carbon. A gain of 2.3 cm{sup {minus}1} with a duration of 250 psec was observed in Ni-like Ta at 44.83 A (a wavelength close to optimal for holographic imaging of live cells). Ni-like W produced a gain of 2.6 cm{sup {minus}1} with a total of seven gainlengths of amplification at 43.18 A. This is the first demonstration of an x-ray amplifier on the short-wavelength side of the carbon {ital K} edge, within the water window.'' Both lasers should be scalable to coherent power sufficient for holographic imaging and other applications.
