| 摘 要： | 报道了高功率全固态腔内和腔外倍频两种绿光激光器研究进展。腔内倍频绿光激光器采用L型腔双棒串接结构，在重复频率10 kHz时，用三硼酸锂晶体倍频获得绿光功率186 W，光-光效率达15.8%。腔外倍频绿光激光器采用主振荡和功率放大器，在重复频率400 Hz时，获得基频激光单脉冲能量1.2 J，采用Ⅱ类相位匹配KTP晶体腔外倍频，获得525 mJ的绿光输出，倍频效率为43.7%。采用偏振合成技术获得了单脉冲能量大于1 J的绿光输出。在该激光放大器实验装置上，进行了双模块热效应补偿技术和受激布里渊散射相位共轭技术实验研究，改善了激光光束质量。

| Abstract: | The paper reports the research progress in all-solid-state high power green laser. The intracavity frequency-doubled green laser adopts the two-rod L-shaped cavity. When the pumping power is 1 174 W, the 532 nm output power is 186 W and the optical-optical efficiency is 15.8% with LBO frequency-doubling crystal. A diode pumped master oscillator power amplifier laser with output pulse energy of 1.2 J at 400 Hz repetition rate is demonstrated. With a type Ⅱ phase matched KTP crystal, 525 mJ green light pulse energy at 400 Hz repetition rate is obtained. The frequency conversion efficiency is about 43.7%. The laser energy of the double beam laser is more than 1 J with the technique of polarization synthesis. Moreover, a 90°quartz rotator is placed between the two laser modules to fulfill t |
