| 摘 要： | 大功率千赫兹激光器作为雷达系统的核心部分之一,在大气科学的研究中显得极为重要。实现大功率千赫兹激光器的可行方式之一是采用主振荡功率放大器。为了获得窄脉宽、高光束质量的千赫兹主振荡器,采用二极管端面抽运的千赫兹电光调QNd:YAG激光器的方法,进行了理论分析和实验验证,取得了重复频率1kHz、脉冲宽度5ns、单脉冲能量2.7mJ的1064nm激光输出,光光转换效率40%、光束质量M2=1.2。结果表明,该研究为1kHz,500W,10ns绿光主振荡功率放大器提供了合格的种子源。

| Abstract: | As one of the core parts of a radar system, high-power kHz laser is extremely important in the study of atmospheric science. It is one of the feasible ways to achieve high-power kHz laser master oscillator power amplifier.In order to get the narrow pulse width, high beam quality kHz master oscillator laser, a diode end-pumped kHz electro-optic Q-switched Nd∶YAG laser was used in experiments. A laser at 1064nm was obtained with repetition rate of 1kHz, pulse width of 5ns, pulse energy of 2.7mJ, optical-optical efficiency of 40%, M2=1.2. The results show that this laser provides a qualified seed source for 1kHz, 500W, 10ns green master oscillator power amplifiers. |
