Abstract

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:Al₂O₃ laser. In spite of a significant time difference (as much as 2 $\mathit{\mu }\mathrm{s}$) 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 $<3 \mathrm{ns}$, depending on the combination of the two wavelengths. A sum output energy of $\sim 41 \mathrm{mJ}/\mathrm{pulse}$ was obtained for a pair of 780- and 810-nm pulses with a typical pulse width of $\sim 30 \mathrm{ns}$ (FWHM).
