摘要
We report a novel, to the best of our knowledge, approach for injection seeding of pulsed optical parametric oscillators (OPOs), which can provide spectral control over the full tuning range. Bandwidth reduction down to single-mode operation is realized across the pulsed tuning range by deploying a hybrid design, where a continuous-wave (cw) OPO injection seeds the pulsed OPO in a single composite cavity. By exploiting two identical MgO-doped periodically poled lithium niobate crystals, the hybrid OPO provides signal pulses with a single-frequency linewidth as narrow as 7.2 MHz across 1510–1677 nm. The effect of cw injection seeding on pulsed OPO operation is also confirmed by reduced rise time, increased pump depletion, major reduction in threshold, and substantial enhancement in output power and extraction efficiency.
