We report the demonstration of a gain-saturated 10.9 nm tabletop soft x-ray laser operating at 1 Hz repetition rate. Lasing occurs by collisional electron impact excitation in the 4dS01-->4pP11 transition of nickel-like Te in a line-focus plasma heated by a chirped-pulse-amplification Ti:sapphire laser. With an average power of 1muW and pulse energy up to approximately 2microJ, this laser extends the ability to conduct tabletop laser experiments to a shorter wavelength.
我们展示了一种增益饱和的 10.9nm 台式软 X 射线激光，其重复频率为 1Hz。激光通过在啁啾脉冲放大钛宝石激光加热的线聚焦等离子体中，在镍样碲的 4dS01-->4pP11 跃迁中通过碰撞电子冲击激发来实现。在平均功率为 1μW 和脉冲能量高达约 2μJ 的情况下，这种激光将进行台式激光实验的能力扩展到了更短的波长。
