摘　　要：针对板条激光器输出光束形态为条形的特点,分析了各种光束质量评价方法对板条激光器输出光束质量评价的适用性,并选出了一种最适合板条激光光束质量的评价方法。高功率板条激光器要输出高光束质量的光束,可以在板条激光器的设计阶段采用相关技术来提高输出光束质量,对输出后有像差的光束可经整形后,采用自适应光学技术来提高光束质量。Several evaluation methods for laser beam quality were reviewed,their applicability for the outline characteristic of slab laser was analyzed and an evaluation method for slab laser was chosen.To get good beam quality of slab laser,a correlative technique can be used to improve beam quality of slab laser while the laser is designed.When the shape of the rectangle beam of slab laser is changed,the adaptive optics technique can be used to improve beam quality.For output beam of the practical slab laser,good quality beam can be got after adaptive optics is used.
