Space- and time-resolved investigation of gain lines in Na-like copper

We report space- and time-resolved measurements of the gain coefficient for four gain lines in sodium-like copper. The lines investigated include the twoΔn = 1 transitions 5g−4f and 5f−4d at 11.1 nm and 10.3nm and the twoΔn = 2 transitions 6g−4f and 6f−4d at 7.2 nm, and 6.9 nm. The investigations were carried out for four irradiation intensities from 4 × 1012 W/cm2 to 3 × 1013 W/cm2 using the Asterix IV high-power iodine laser at Garching (wavelength 1.315 µm, pulse duration 450 ps).
The main results may be summarized as follows: On varying the laser intensity it was found that the highest values of the gain could be seen at an irradiation of 8 × 1012 W/cm2. For theΔn = 1 lines the spatial maximum of the gain occurred at a distance of 300 µm from the target, and for theΔn = 2 lines at 200 µm. The temporal gain maximum occurred at a time of 1.8 ns after the pulse maximum. The gain values range up to 2.6 cm−1.
