Rw. Farley et Pd. Dao, DEVELOPMENT OF AN INTRACAVITY-SUMMED MULTIPLE-WAVELENGTH ND-YAG LASERFOR A RUGGED, SOLID-STATE SODIUM LIDAR SYSTEM, Applied optics, 34(21), 1995, pp. 4269-4273
A single-cavity solid-state laser that is resonant with sodium D-2 abs
orption is reported. Simultaneous 1.06- and 1.32-mu m emission from a
Q-switched Nd:YAG laser is summed with an intracavity type II KTP crys
tal. A single-intracavity etalon is sufficient to provide a time-avera
ged linewidth of 1.7 GHz at 589 nm.
