Abstract
Intense lasing at 18.9 and 20.3 nm in nickel-like molybdenum and niobium ions has been observed by using two 200 ps laser pulses with total energy of 50 J at 1.053 μm from XingGuang II laser facility. Their gain coefficients were measured to be 1.6 and 1.5 cm-1, respectively. This shows the possibility of extending Ni-like x-ray lasing in low-Z elements and paves the way towards small scale x-ray lasers for applications at university laboratories.
