Abstract A resonantly photo-pumped soft x-ray laser process is studied for neon-like iron ions with an automatic line match scheme. The special advantages of this scheme are shown. The temporal characteristics of lasing gains and their dependences on the pump strength and electron density are investigated. Unlike the electron-collisional excitation and some other photo-pumped excitation schemes, it is demonstrated that main photopumped gains come from 2p-4d-3p-3s transition channels. Using the experimental data of pump strengths from a non-LTE plasma produced in our experiment as input data, our model yields a peak gain of 5.6 cm−1, 2.8 cm−1 and 1.9 cm−1 on the dominant lasing transitions at 38.74 nm, 25.47 nm and 20.46 nm.
