Abstract

We propose a laser scheme in which the upper levels of a lasing ion are pumped by narrow, quasi-continuous band radiation. In particular, we consider pumping of neon-like chlorine ions by N band radiation of Pb from 41 Å to 44 Å. We calculate small signal gain coefficients for the n=4 - n=3 transitions in neon-like chlorine. Both steady-state and time-dependent calculations have shown that the largest gain is found for the 2s²2p_1/2^-14f_5/2(J=2) - 2s²2p_1/2^-13d_3/2(J=l) transition at a wavelength of 264 A, with a value of 5 cm^-1. Achieving this value for the gain would require a pump radiation which has a brightness of 0.01 photons/mode, corresponding to an intensity of 1.6×10¹²
