Abstract

The performance of a diode-pumped c-cut $\mathrm{Nd}\text{:}\mathrm{MgO}\text{:}{\mathrm{LiNbO}}_3$ laser at 1093 nm was demonstrated. Under an absorbed pump power of 7.450 W, a maximum continuous wave output power of 1.570 W was obtained, corresponding to a slope efficiency of 26.0%. For passive Q-switching operation, 24 ns pulses were observed with a repetition rate of 17.1 kHz, resulting in a peak power of 1357 W. The experimental results were theoretically analyzed by a rate equation model, in which the Gaussian spatial distribution of the intracavity photon density was taken into account.
