摘　　要：在高功率密度激光作用下，某些线性介质中会产生非线性自聚焦现象。非线性自聚焦的产生过程具有丰富的内涵。在一定条件下它是可控的．受控成模后在线性介质中传播保持其模不变。Under high power density laser action, in some linear media could produce nonlinear self-focusing. There are rich physical contents in nonlinear self-focusing process. It could be controlled under some conditions. Controlled beam becomes mode which is unchanged propagation in linear media.

关 键 词：非线性自聚焦 可控性 新光束 二氧化碳激光器
