Abstract

The rate equations for the pumping of the Nd3+ system are simplified to a single differential equation. This is solved for the population of the 4F3/2 level, N, under a pump waveform, At2e-bt, assuming that the lifetime of the state is constant. The optimum Q-switch time (time at which N and the output energy of the laser pulse are maximum) is then calculated. The optimum Q-switch time is given as a function of pump input energy for a 5-wt% Nd2O3 in barium crown glass, 80-mm-long clad laser rod, pumped with an FX38 flash tube driven by a simple LC circuit. From these results, the apparent lifetime of the 4F3/2, level was shown to decrease from 157 µsec with 67.5-J input to 57 µsec with a 144-J input.
