| Abstract: | Thermal blooming and phase compensation correction for thermal blooming is numerically simulated in this paper.From the results of simulation,it is showed that Strehl ratio gets high and optical beam quality gets good.And the scaling law of thermal blooming after compensation correction is derived.It is found that critical power of thermal blooming after compensation correction is three times more than when not compensated. |

| Keywords: | thermal blooming phase compensation correction scaling law |
