Further, a maximal output power of 9.4W, vertical divergence angle of 32 °, and threshold current density of 239A/ cm2 can be obtained by adapting broad waveguide layers.

采用宽波导结构可以得到器件的最大输出功率为9.4W，发散角为32°，阈值电流密度为239A/cm2。

And the divergence angle of pumping beam and the off axis pumping influenced t.

且泵浦光的发散角和在偏轴方向的泵浦光对参量光线宽的影响较大.

The patterns show that divergence of the emerging beam increases with the dihedral angle offset up to completely separate to six beams;

通过衍射图可以看出出射光束的发散程度随着角度误差的增加而增加，直至完全分离成六束光束。

Calculated results show that when the Al-content of the waveguide and cladding layers are 0.4 and 0.5 respectively, a maximal output power of 11.2W, vertical divergence angle of 19 °, and threshold current density of 266A/ cm2 can be achieved by adapting narrow waveguide layers;

根据计算结果可知：当波导层和限制层铝组分为0.4和0.5时，采用窄波导结构可以获得器件的最大输出功率为11.2W，发散角为19°，阈值电流密度为266A/cm2；

Choosing three cases of Al-content of the waveguide layer and the cladding layer, we calculate and analyze the dependences of the optical confinement factor, maximal output power, vertical divergence angle, and threshold current density on the thickness of the waveguide layer.

选取了三种情况的波导层和限制层的铝组分，分别计算和分析了波导层厚度与激光器光限制因子、最大出光功率、垂直发散角和阈值电流密度的函数关系。
