The results show that due to the effect of laser beam quality on focal beam waist radius,focal angle and focal length,laser beam quality decides the beam focusing ability and the processing capacity of laser system.

结果表明，光束质量对聚焦光束的焦斑、聚焦角和焦深的影响不仅体现了激光源的可聚焦性，而且也标志了激光源的可加工能力，这是聚焦系统和焦点位置在选择过程中应该考虑的重要因素。

It's M2 factor is approaching the ideal value 1 and the beam intensity profile remains Gauss Profile. Laser beam with good propagation and focus characters. The beam can propagate a long way and can be focused with lens with long focal distance. The focal beam waist radius is 134μm, the focal distanced of the focus lens is 300mm. It's focal depth is about 5mm and the focal shift is about 1mm in the range of processing (3m).

结果表明，Slab CO2激光器具有高光束质量，其M2因子非常接近1的理想值；激光束具有良好的传输和聚焦性能，可以长距离传输；使用焦距为300mm的聚焦镜聚焦，聚焦光斑的束腰半径约为134μm，光束横截面能量分布接近理想的高斯分布，焦深约为5mm，在加工范围内(3m)，激光束的焦点漂移量大约为1mm。

The electron beam is moved/scanned along the anode surface to multiple focal positions.

电子束沿阳极表面移动/扫描到多个焦点位置。
