Abstract : A theory of the four-level solid-state laser has been applied to the case of an unsaturated Nd(3+)-glass pulsed laser amplifier operating at power levels in the order of 1 MW. Equations for flux density and population inversion have been derived which take into account the degeneracies and splittings of the laser levels. Experiments made with a Q-switched oscillator-amplifier structure validate the predicted exponential dependence of amplifier gain on pumping, over the range of energies applied. (Author)
