The transient-excitation pumping scheme, in which a picosecond duration pulse rapidly heats the plasma preformed by a low-intensity nanosecond pulse, was used to pump the Ne-like germanium, J = 0-1 transition at 19.6 nm. A small-signal gain coefficient of 30 cm(-1) was measured for targets less than or equal to 5 mm long. (C) 1998 Optical Society of America.
