根据较为完整的衍射原理，设计λ／2几何厚度的位相片并将其置于腔内尾镜上，在十瓦级封离型CO2激光器上实现了等效光束质量因子小于1的新光束。接着，在百瓦级、千瓦级快速轴流CO2激光器上实现了高光束质量激光束。这些可称之为第一代激光新光束。最后，提出和设计了一种带有突变反射率输出镜的激光谐振腔，在2000W的横流CO2激光器上实现了1000W准基模新光束。这可称之为第二代激光新光束。
According to the more complete diffraction principle, a λ / 2 geometry thickness photo was designed and placed on a cavity end mirror. A new beam with an equivalent beam quality factor less than 1 was achieved on a 10-watt sealed CO2 laser. Next, a high-beam-quality laser beam was achieved on a 100-watt, kilowatt, fast-axial CO2 laser. These can be called the first generation of new laser beam. Finally, a laser resonant cavity with an abrupt reflectivity output mirror was proposed and designed to achieve a 1000W quasi-fundamental new beam on a 2000W cross-flow CO2 laser. This can be called a new generation of laser beam.
