| 摘 要： | 以激光二极管(LD)环形阵列侧面抽运Nd:YLF棒高增益放大器模块为基础，在经典的平凹驻波腔中加人一片Cr^4 ：YAG晶体作为被动Q开关，利用被动Q开关本身所具有的振荡选模功能以及两端不镀膜的Nd：YLF棒所具有的标准具效应，简便地实现了稳定的单脉冲、单纵模调Q输出。振荡器输出脉冲平均宽度为9．3ns，脉冲宽度稳定性达到8％(RMS)；输出脉冲平均能量为1．218mJ；单脉冲能量稳定度优于3％(RMS)，对应峰值功率达到O．13MW。同时该振荡器长时间工作过程中单纵模输出几率始终优于99％，这种单纵模振荡器结构简单，性能稳定可靠，适合于实际应用以及产品化。 |

| Abstract: | Based on the ring-shaped laser-diode array side-pumped Nd:YLF high gain amplifier and the conventional plan-concave resonator, a simple structure single-longitudinal-mode single-pulse Q-switched oscillator is demonstrated by taking advantages of mode-selecting property of passive Q-switches (Cr4+:YAG crystal) and etalons (formed by two end of uncoated Nd:YLF rod). The average pulse width is 9.3 ns, the average energy is 1.218 mJ, the pulse width stability is 8% by RMS and the pulse energy stability is 3% by RMS and the output pulse reaches the peak-power of 0.13 MW. This kind of oscillator holds the excellent single-longitudinal mode probability great than 99% in long running time. Keep in mind of its simplicity and unsensible to the change of working condition, it is preferred to put this kind of oscillator into practical usage in these situations where accurate time sequence is not required. |
