A flash-lamp pumped electro-optically Q-switched dual tunable wavelength Nd:Glass laser is demonstrated. An Nd:Glass rod was selected as the laser medium and a DKDP crystal was employed as the Q-switch. A cubic polarizer was placed in the cavity to divide the randomly polarized radiation into two orthogonally polarized beams. The two beams were tuned by two Littman-gratings and output independently. For Q-switched operation, the tuning range was 1050.1 - 1061.6 nm and 1050.5 - 1060.2 nm for the horizontal and vertical polarizations, respectively. When the horizontally polarized output was fixed at 1059.1 nm, the synchronized vertically polarized one can be tuned from 1051.5 to 1057.5 nm.
