我们构建了一个同步泵浦参量振荡器，它使用温度调谐、非临界相位匹配的 LiB3O5 作为非线性介质。我们使用两种不同的泵浦源同步泵浦该 LiB3O5 参量振荡器。第一个是连续波锁模钛蓝宝石激光器，可产生 2 W 的 100-fs 脉冲，波长接近 800 nm。使用该泵浦源，我们生成了短至 40 fs 的脉冲，或高达 550 mW 的平均功率。我们通过生成 100-fs 互相关来演示泵浦和信号脉冲之间的同步。我们的第二个泵浦源是新型倍频二极管泵浦 Nd:YVO4 激光器，可在 532 nm 处产生 2 W 6 ps 脉冲。我们通过这种全固态系统的腔外色散补偿产生了短至 270 fs 的脉冲。
We have constructed a synchronously pumped parametric oscillator that uses temperature-tuned, noncritically phase-matched LiB3O5 as the nonlinear medium. We have synchronously pumped this LiB3O5 parametric oscillator with two different pump sources. The first is a cw mode-locked Ti:sapphire laser that produces 2 W of 100-fs pulses near 800 nm. Using this pump source, we have generated pulses as short as 40 fs, or as much as 550 mW of average power. We demonstrate the synchronization between the pump and the signal pulses by generating a 100-fs cross correlation. Our second pump source is a novel frequency-doubled diode-pumped Nd:YVO4 laser that produces 2 W of 6-ps pulses at 532 nm. We have generated pulses as short as 270 fs with extracavity dispersion compensation from this all-solid-state system.
