Gain lifetime measurement of a Ni-like Ag soft X-ray laser

Experimental results of a two-stage Ni-like Ag soft X-ray laser operated in a seed-amplifier configuration are presented. Both targets were pumped applying the double-pulse grazing incidence technique with intrinsic travelling wave excitation. The injection of the seed soft X-ray laser into the amplifier target was realized by a spherical mirror. The results show amplification of the seed soft X-ray laser and allow for a direct measurement of the gain lifetime. The experimental configuration is suitable for providing valuable input for computational simulations.
