A mid-infrared ${{\rm ZnGeP}_2}$ optical parametric oscillator pumped by a ${{\rm Tm}^{3 +}}$-doped fiber laser is reported, providing pulse energies of $230 ;\unicode{x00B5}{\rm J}$, pulse widths of 40 ns, and peak powers of ${\sim}6;{\rm kW} $ with excellent efficiency and beam quality. The pump source is an actively $Q$-switched single oscillator optimized to generate high pulse energies.
报道了一种由掺铥光纤激光器泵浦的中红外ZnGeP₂光学参量振荡器,其脉冲能量为230 μJ,脉冲宽度为40 ns,峰值功率约为6 kW,具有优异的效率和光束质量。泵浦源是一个经过主动调Q优化的单振荡器,用于产生高脉冲能量。
