Development of an intracavity-summed multiple-wavelength Nd:YAG laser for a rugged, solid-state sodium lidar system.
A single-cavity solid-state laser that is resonant with sodium D(2) absorption is reported. Simultaneous 1.06- and 1.32-µm emission from a Q-switched Nd:YAG laser is summed with an intracavity type II KTP crystal. A single-intracavity étalon is sufficient to provide a time-averaged linewidth of 1.7 GHz at 589 nm.
