| 摘 要： | 基于种子注入技术、干涉法腔模锁定方案以及自滤波非稳腔技术,设计并研制出一套单纵单横电光调Q脉冲激光器系统。该系统输出的基波(波长1064nm)能量达到600mJ,倍频后绿光能量达到300mJ,发散角接近衍射极限,线宽接近傅里叶变换极限,在强气流强振动环境中单纵模的锁定概率为100%。实验观测了种子注入对巨脉冲建立时间、光斑模式以及能量的影响。该系统可应用于受激布里渊散射(SBS)、大视场风洞全息以及光学合成孔径等研究领域。 |

| Abstract: | A single axial and transverse mode Q-switched pulsed laser system is demonstrated based on injection seeding and fast resonance detection technique combined with self filtering unstable resonator. 600 mJ energy at 1064 nm and 300 mJ energy when frequency-doubled, are achieved at Fourier-transform limit and with a beam divergence near diffraction-limit. The system is also characterized by the long-term stability in high vibration environments. The influence of injection-seeding on giant pulse setup time, beam-spot mode, and energy is observed experimentally. The perfect laser radiation is desirable in the area such as nonlinear optics, optical synthesized aperture and high-resolution spectroscopy. |
| Keywords: | laser technique single axial and transverse mode laser injection-seeding self filtering unstable resonator interferometry |
