Longitudinal pumping of CW Ti:sapphire oscillators is considered in order to predict the power output of such oscillators using folded, astigmatically compensated cavities. The model predicts how the oscillator performance is affected by the selection of Ti/sup 3+/ concentration, material figure of merit (FOM), rod length, and pump and cavity mode waists. Experimental results are reported for broad-band CW oscillators pumped by CW argon ion lasers, and these results are shown to be in excellent agreement with theory. Nearly 30 percent slope efficiency is achieved with a four-mirror folded cavity and even higher efficiencies are predicted for optimizing pumping. The analysis is not limited to Ti:sapphire lasers and may be applied to other longitudinally pumped laser media in which the modes are described by low-order Gaussian profiles.
