Phys. Rev. A 65, 033810 (2002) [4 pages]Demonstration of a 2-ps transient x-ray laserReceived 3 July 2001; published 8 February 2002 A time-resolved measurement of the output from the Ni-like Ag transient-collisional-excitation x-ray laser is described. An ultrafast x-ray streak camera was used to diagnose the output of the J=0⃗1 4d-4p lasing line at 13.9 nm. The full width at half maximum duration of the x-ray pulse is measured to be of 1.9±0.7 ps at optimum conditions of pump laser irradiation. This is the shortest x-ray laser duration directly demonstrated to date and illustrates the great potential of transient x-ray lasers as a high brightness, picosecond x-ray source for applications. © 2002 The American Physical Society URL:
