We obtain high peak power pulses in megawatt range of the first (1181 nm), second (1321 nm), and third order (1500 nm) Stokes radiation from self-conversion of the 1067-nm laser radiation based on Nd:KGW laser. The maximum output energy of the first order Stokes laser is 35.3 mJ, which is to our knowledge, the highest reported energy in an intracavity Q-switched laser. The third order Stokes pulse is obtained in an intracavity Q-switched laser.

A new technique for seed-injection locking of single-axial-mode (SAM) Q-switched Nd:YAG laser is reported. The technique called energy reduction (ER) is utilized when SAM operation is locked to design its feedback scheme. This method ensures long-term 100% seed-injection locking performance and the pulsed SAM output energy can reach as high as 200 mJ. Both temporal and spatial interferometric experiments have been executed to confirm the SAM oscillation.

针对5种主次吸收峰严重交叠的红外混合气体定量分析问题，提出一种基于高阶累积量分析方法，该方法将重叠的吸收谱线映射到彼此相互分开的四阶累积量空间；在四阶累积量空间中提出一种基于正则理论和最小二乘相结合的支持向量机多维数据建模方法．在小样本下有效地提高了模型的准确度和收敛速度．实验结果表明，该方法使系统的引用误差小于4%，因而能满足外场使用的要求．
