Abstract
We report the demonstration of a gain-saturated tabletop soft x-ray laser operating at repetition rate. Lasing occurs by collisional electron impact excitation in the transition of nickel-like Te in a line-focus plasma heated by a chirped-pulse-amplification Ti:sapphire laser. With an average power of and pulse energy up to , this laser extends the ability to conduct tabletop laser experiments to a shorter wavelength.
