We have demonstrated repetitive operation of a table-top lambda=13.9 nm Ni-like Ag soft-x-ray laser that generates laser pulses with 10 microJ energy. The soft-x-ray laser is enabled by a Ti:sapphire laser pumped by high-repetition-rate frequency-doubled high-energy Nd:glass slab amplifiers. Soft-x-ray laser operation at 2.5 Hz repetition rate resulted in 20 microwatt average power.

We review recent advances in the development of high repetition rate table-top soft X-ray lasers that includes their extension to wavelengths down to 10.9 nm and the first demonstration of an all-diode-pumped soft x-ray laser.
