Abstract

Plasma-based soft x-ray lasers (SXRL) enable experiments requiring bright, high energy, soft x-ray laser pulses to be conducted in compact facilities. Recent advances in high energy, high repetition rate, ultrashort pulse solid state lasers now make it possible to extend their wavelenght range, increase their repetition rates, and improve their efficiency. Recently we extended the operation of gain-saturated compact repetitive x-ray lasers down to λ=6.85 nm in Ni-like Gd [1]. Isoelectronic scaling of these collisionally excited laser transitions produced strong lasing at 6.67 nm and 6.11 nm in Ni-like Tb and amplification at 6.41 nm and 5.85 nm in Ni-like Dy [1]. This recent progress will be summarized, and efforts to further extend laser operation to shorter wavelengths will be reviewed. We will also discuss the possibility of increasing the efficiency of plasma-based soft x-ray lasers by controlling the pulse shape of the pump pulses. Prospects of these SXRL will be discussed.
