In the second part of of this thesis, we firstly derivate the operation condition of intracavity SHG of dualwavelength laser from the rate equation, and then numerically calculate the relationship between the laser operation parpmeters and the pumping powers. And then we discuss two possible ways to get balancing outputs of the harmonic waves of the two wavelengths. By comparing the two ways, we find that the method by increasing the geometrical factor of 1079. 5nm SHG has the higher efficiency than the method by adding the additional loss of 1079. 5nm basic wave. Besides, the first method is easier to realize in experiment than the second method.

本论文第二部分从速率方程出发，通过求解速率方程的稳态解得到了Nd：YAP腔内倍频双波长激光的连续运转条件，数值计算得到了随泵浦功率变化的激光运转情况；计算、分析了通过增加主波长的倍频耦合几何因子和增加主波长的腔内损耗两种方法获得均衡的双波长倍频输出的运转情况，通过二者的比较，发现增加倍频耦合几何因子的方法比增加损耗的方法效率更高，而且在实验上更易于实现。

The phosphorus forms and BAP vary with horizontal and vertical positions. The total phosphorus, inorganic phosphorus, BAY, and iron-phosphorus contents were high at a depth of 0~20 cm at the first sampling point, and then decreased at 20-40 cm of depth. This shows that the potential release capacity of P at 0-20 cm of depth is higher. The concentrations of total phosphorus and inorganic phosphorus decreased at 0~20 cm of depth and increased at 20~40 cm of depth at the second sampling point, but BAY and Fe-P increased along with the depth consistently. This shows that the deeper layer at the second sampling point had a higher potential release capacity of phosphorus.
