Abstract

Saturated tabletop lasers operating at $5 Hz$ repetition rate with average powers $> 1 μ W$ were demonstrated at wavelengths between 16.5 and $13.9 nm$ in the $4 d {}^{1}S_{0} - 4 p {}^{1}P_{1}$ transitions of Ni-like ions. The results were obtained using picosecond laser heating pulses with an energy of only $1 J$ by optimizing the angle of incidence for maximum energy deposition. Lasing was also observed for shorter wavelength transitions of the same isoelectronic sequence, with amplification in the $11.9 nm$ line of Ni-like Sn approaching gain saturation, and progressively reduced gain for wavelengths as low as $10.9 nm$ for Ni-like Te. These high repetition rate soft x-ray lasers will enable new applications in science and the development of unique metrology and processing tools for industry.
