Perfect synchronization of two different wavelength oscillations that are tunable within a range of 770-820 nm is obtained from a self-injection-seeded Q-switched flash-lamp-pumped Ti:Al(2)O(3)laser. In spite of a significant time difference (as much as 2 micros) between the two seed pulses generated in the master oscillator, a common Pockels cell switch synchronizes the two injection-seeded Q-switched pulses growing from spatially separated slave oscillators in a common laser rod within a delay time of <3 ns , depending on the combination of the two wavelengths. A sum output energy of approximately 41 mJ/pulse was obtained for a pair of 780- and 810-nm pulses with a typical pulse width of approximately 30 ns (FWHM).
